Note:
1.For thePV under-voltage point,refer to parameter A5-06.A hysteresis voltage of approximately 20V is set to prevent relay chatter in the main circuit.
2.Thedefault under-voltage and over-voltage points for the MPPT macro can be checked in parameters A5-06 and A5-09,respectively.
3.For PV maximum power point tracking(MPPT) method, set _ { { H 0 - 2 9 } } = 5 0 1 toautomatically obtain the PV open-circuit voltage.
4.For PV constant voltage tracking(CVT) macro method,set { H } 0 { - } 2 9 = 5 0 2 andE 3 1 - 0 1 = 0 .The open-circuit voltage can be manually modified via digital inputin B1-03.
5.When B1-23 (sleep count)is notO,the sleep delay timer is active.Once the sleep duration is reached,the inverter will wake up and resume operation.The wake-up time will incrementally extend based on the count in B1-23.
6.When B1 . 0 1 = 1 ,the open-circuit voltage is automatically obtained,and parameters B1-O5,B1-07, and B1-19 will adjust proportionally.

Chapter 8 Communication

8.1ParameterCommunicationAddress

Communication data can be divided into functional code data and non functional code data,the latter including running commands,running status,running parameters,alarm information, etc. Parameterdata

The function code data is an important setting parameter for the frequency converter,which includes H group and A group function parameters.The parameter groups are as follows:

The definition of parameter data communication addresses isas follows:

1.When reading data with communication function codes

Forparameter data in groups { H } 0 ~ { H } { F } and \mathbf { A } 0 ~ \mathbf { A } { F } ,the upper 16 bits of the communication address directly represent the function group No.,while the lower16 bits represent the parameter's sequence No.within the function group.

In the functional group,the No.ing is as follows:

H0-16 functional parameters,with communication address FO1oH,where FOH represents HO group functional parameters and1OH represents the hexadecimal data format of parameter No.16 in the functional group.

The AC-08 functional parameter has a communication address of ACO8,where ACH represents the AC group functional parameter and O8H represents the hexadecimal data format of parameter No.8 in the functional group.

2.When writing function code data for communication

For { H } 0 ~ { H } { F } group parameter data,the communication address is divided into { 0 0 } ~ 0 { F } or { H } 0 ~ { H F } based on whether it is writen into EEPROM.The lower 16 bits directly represent the sequence No.of the parameter in the functional group.For example,

Write functional parameter H0-16:

Whenthere is no need to write to EEPROM,its communicationaddress is 0010H;

WhenwritingtoEEPROM,itscommunicationaddressisF010H.

When writing EEPROM data for communication,for \mathbf { A } \mathbf { 0 } ~ \mathbf { A } \mathbf { F } group function code data, the upper sixteen bits of the communicationaddress aredistinguished as 1 0 ~ 4 { F } or \mathbf { A } \mathbf { 0 } ~ \mathbf { A } \mathbf { F } ，andthelower sixteen bits are directly the serial No.of the function code in the function group.For example,

Whenthereisnoneed towritetoEEPROM,itscommunicationaddressis 4C08H; WhenwritingtoEEPROM,itscommunicationaddressisAC08H. Non-parametric data

1.Status Data

Statusdatais divided into U-group monitoringparameters,inverter fault descriptions,and inverter operatingstatus.
GroupParameterMonitoringParameters
{ U } 0 ~ { U } { F } ,with the high16 bits of their communication addresses ranging from 7 0 ~ 7 { F } The low16 bits represent the sequence No.of the monitoring parameter within the group.For example: Uo-11 has a communication address of 700BH.
Inverter Fault Description
When reading the inverter fault description via communication,the communicationaddress is fixed at 8 0 0 0 { H } .The host computer can obtain the current inverter fault code by reading the dataatthis address. Descriptions of the fault codes can be found in the definitions of parameter F9-14.
Inverter Operating Status
When reading the inverter operating status via communication,the communication address is fixed at 3000H.The host computer can obtain the current inverter operating status information by reading the data at thisaddress.The definitions areas follows:

2.Control Parameters

Control parametersare divided into:control commands,digital output terminalcontrol,analog output A01 control,analog output AO2 control,and high-speed pulse (FMP) output control.
Control Commands
When Ho-02(Command Source) is set to 2:Communication Control,the host computercan use this communication address to issue start/stop and other related commands to the inverter.The control command definitionsare as follows: Communication Settings
The communication seting values are mainly used for selecting the frequency source,torque upper limit source,V/Fseparation voltage source,PID givensource,PID feedback source,etc.as the given data for communication timing in frequency converters.Its communication address is 1 0 0 0 { H } ，and when the upper computer sets the communication address value,its data range is - 1 0 0 0 0 ~ 1 0 0 0 0 0 corresponding to a relative given value of - 1 0 0 . 0 0 % ~ 1 0 0 . 0 0 % ：
Digital OutputTerminal Control
When the digital output terminal function is selected as 20:communication control,the upper computer can control the digital output terminal of the frequency converter through this communication address,defined as follows:

Analog output AO1,AO2,high-speed pulse output FMP control When the analog output AO1,AO2,high-speed pulse output FMP output function is selected as 1: communication seting,the upper computer can control the analog and high-speed pulse output of the frequency converter through this communicationaddress,defined as follows:

When it is necessary to initialize the parameters of the frequency converter through the upper computer, this function needs to be used.

If HP-0O (user password） is not O，password verification needs to be performed through communication first.After verification,the upper computer will perform parameter initialization operation 30 seconds later.

The communication address for user password verification is 1FooH. Simply write the correct user password into this address to complete the password verification.The address for parameter initialization in communicationis 1FO1H,and its data content is defined as follows:

ModbusProtocol

Overview

Provide RS485 communication interface and support Modbus RTU slave communication protocol.Users can achieve centralized control through computers or PLCs,set frequency converter operation commands,modifyor read parameters,and read the working status and fault information of the frequency converter through this communication protocol.

This serial communication protocol defines the content and format of information transmitted in serial communication.This includes: host polling (or broadcasting) format.The encoding method of the host includes parameters for required actions,data transmission,and error checking.The response of the slave machine also adopts the same structure,including action confirmation,data return,and error verification.If the machine encounters an error when receiving information or cannot complete theactions required by the host,it will organizea fault messageas fedback to the host.

Applicationmethod

The frequency converter is connected to a "single master multi slave"PC/PLC control network withRS485 busasa communicationslave.

Topology

Single-host multi-slave system.Each communication device in the network has a unique slave address,withone device actingas thecommunication host (usuallyaPC,PLC,HMI,etc.),actively initiating communication and performing parameter read or write operationson the slave.Other devices act as communication slaves,responding to inquiries or communication operations from the host to the local machine.Only one device can send data at a time,while the other devices are in a receiving state.

Thesetting range of the slaveaddressis1-247,with O being the broadcast communication address.The slave address in the network must be unique.

Communicationtransmissionmethod

Asynchronous serial,half duplex transmission mode.In the process of serial asynchronous communication,data is sent in the form of messges,one frame ata time.According to the Modbus RTU protocol,when the idle time on the communication data line is greater than the transmission time of3.5Byte,itindicatesthestartofanewcommunication frame.

The built-incommunication protocol is Modbus RTU slave communication protocol,which can respond to the host's "query/command"or make corresponding actions based on the host's "query/command"and respond to communicationdata.

The host can refer to a personal computer (PC),industrial control equipment,or programmable logic controller (PLC),etc.The host can communicate with aspecific slave individuallyor broadcast information toall slaves.For the individual access "query/command"of the host,the accessed slave should return a response frame.For the broadcast information sent by the host,the slave does not need to provide feedback to the host.

Communicationdataframestructure

The communication data format of Modbus RTU protocol is as follows.The frequency converter only supports reading or writing Word type parameters,and the corresponding communication read operation command is 0 x 0 ^ { 3 } .The write operation command is 0 { x } 0 6 ，the multi-write operation command is 0 { x } 1 0 ,and byte or bit read/write operations are not supported:

>3.5Byte 1Byte1Byte 2Byte 2Byte 2Byte Master station reads Idle (frame header) so commad Functietsde r CRC_checksum Idle → CalculateCRCcheck

In theory,the upper computer can read multiple consecutive parameters at once (i.e.up to a maximum of12 parameters in n ),but it should be noted thatit cannot cross the last parameter in this parameter group,otherwise it will reply with an error.

If the slave station detects a communication frame error or other reasons causing read and write failures,itwill replywithanerror frame.

Instructions

CRC check error will not receive a response.
Modbusmode follows standard Modbus protocol.

CRC(Cyclic Redundancy Check) uses RTU frame format,and Modbus messages include an error detection field based on CRC method.The CRC domain detects the content of the entire message. The CRC field is two bytes containinga16 bit binary value.Itis calculated bythe transmission device and added to the message.The receiving device recalculates the CRC of the received message and compares itwith the values in thereceived CRCfield.If the two CRCvaluesare not equal,itindicates

thatthereisan errorin the transmission.

CRC stores 0 { x } { F F F F } first,and then calls a process to process the consecutive 8-bit bytes in the message with the value in the current register.Only8-bit data in each byte is valid for CRC,and the start, stop,and parity bits are invalid.

During the CRC generation process,each bit is individually XOR with the register content, resulting inashift towards the least significantbitdirection,with the most significantbit filled with 0. LSB is extracted for detection.IfLSB is1,theregister alone is different from the preset value.If LSB is O,no detection is performed.The entire process needs to be repeated 8 times.After the completion of the lastbit (8th bit),the nextbyte is separately different from the current valueof the register.The value in the final register is the CRC value afterallbytes in the message have been executed.

HF group:parameterscannot be read or changed;
U-group:only readable,parameters cannot be changed.
Some parameters cannot be changed when the frequency converter is in operation,and some parameters cannot be changed regardless of the state of the frequency converter.When changing parameter parameters,it isalso important topayattention to the range,units,and related explanations of the parameters. Due to frequent storage of EEPROM,its lifespan can be reduced.Therefore,some parameters do not need to be stored in communication mode,and only the values in RAM need to be changed.
If it is a { ~ \bf ~ P ~ } group parameter,to achieve this function,simply change the high-order Fof the parameter address toO.If it isaparameter ingroupA,toachieve this function,simplychange thehigh-orderAof the parameter address to 4.The corresponding parameter addresses are represented as follows: High byte: 0 0 ~ 0 { H } (H group), 4 0 ~ 4 { F } (A group)
Lowbyte: { 0 0 } ~ { H F } （2
For example:
Parameter H3-12 is not stored in EEPROMand itsaddress is represented as O30C; parameter A0-05 is not stored in EEPROMand itsaddress is represented as 40o5.Thisaddress indicates that it can only be used for writing to RAMand cannotbe used for reading.When reading,itis an invalid address. Please refer to the table below for the shutdown/operation parameters.

Instruction

The communication setting value is a relative percentage of 1oooo corresponding to 1 0 0 . 0 0 % 元 and - 1 0 0 0 0 corresponding to - 1 0 0 . 0 0 % ofthe frequency dimension data. This percentage is the percentage of the relative maximum frequency (Ho-1O).For the torque dimension data,the percentage is F2-10A2-48 (torque upper limit numerical seting,corresponding to the first and second motors respectively).

Control command input to frequency converter: (write only)

Analog output AO1 control: (write only)

HD group communication parameter description
The HD-OO parameter is used to set the data transmission rate between the upper computer and the frequency converter.Note that the baud rate set between the upper computer and the frequency converter must be consistent,otherwise communication cannot proceed.The higher the baud rate,the faster the communication speed.

The data format set between the upper computer and the frequency converter must be consistent, otherwise communication cannot proceed.

When the local address issetto O,itis the broadcast address,which realizes the broadcasting function of the upper computer.The local address has uniqueness (except for the broadcast address),which is the basis for achieving point-to-point communication between the upper computer and the frequency converter.

Responsedelay:refers to the interval between the end ofdatareception by the frequency converter and the transmisson of data to the upper computer. If the response delay is less than the system processing time,the response delay shall be based on the system processing time.If the response delay is longer than the system processing time,the system shall delay and wait until the response delay time expires before sending the data to the upper computer.

When this parameter is set to a valid value,if the interval between one communication and the next exceeds the communication timeout,the system will report a communication failure error (Err16). Usually,it isset to invalid.If this parameteris set ina continuouscommunicationsystem,the communication status can be monitored.

Explanation:Increasing the carrier frequency can reduce electromagnetic noise,but the temperature rise of the frequency converter will increase,the leakage current of the frequency converter will increase,the output current willincrease,and electromagnetic interference will increase.In the case of acceptable electromagnetic noise,try not to increase the carrier frequency.

Explanation: Increasing acceleration and deceleration time is beneficial for the smooth start and stop of the motor.If the acceleration time is too short, it may easily cause overcurrent protection; If the deceleration is too short,itcan easily cause over-voltage protection,and corresponding brake units should be installed.

9.2External switch start, stop,forward and reverserotation

Set parameter _ { { H 0 - } 0 2 } = 1 and use terminals to control the start and stop of the frequency converter. Set parameter H4-1l and configure the control mode for terminal commands.There are four command modes for terminals,namely two-wire type1,two-wire type2,three-wire type1,and three-wire type 2.

\mathbf { X } 1 ~ \mathbf { X } 5 (HDI) multifunctional input terminals can be arbitrarily selected as external input terminals. The function of \mathbf { X } 1 ~ \mathbf { X } 5 (HDI) input terminals can be selected by setting the values of H4-0o\~H4-09. Fordetailed functiondefinitions,referto the "ParameterList"forthe selectionof { H } 4 { - } 0 0 \left( { X } 1 \right) ~ { H } 4 { - } 0 4 （204号 (X5) terminal functions.

The following introduces commonly used two-wire and three-wire controls

Forexample,X1 terminal isassigned with forward rotation function,andX2 terminal isassigned with reverse rotation function. Connect the forward running switch to terminal Xl and the reverse running switch to terminal X2.

When the control switch SWI is closed and SW2 is open,the motor rotates forward.When the control switch SW1 isopen and SW2 is closed,the motor rotates in reverse.When both SW1 and SW2 are open or closed,the motor does not run.As shown in the following figure.

SW3 is a normally closed button,while SW1 and SW2 are normally open butons.When the SW3 button is closed,press theSW1button to rotate the frequency converterforward,press the SW2buton to rotate the frequencyconverter backward,and when the SW3 buttonis disconnected,the frequency converter stops immediately.During normal startup and operation,it is necessary to keep the SW3 buton closed,and the commands forthe SW1 and SW2 buttons willtake effect immediately upon the closing action.

9.3 Power on automatic operation

Power on operation refers to the automatic start and operation of the frequency converter without the need to press the start button after powering it on.

9.4Application Cases of Constant Pressure Water Supply

When using macro parameters,it is important to note that the macro functions of this machine are intended to reduce the No.of function code parameters configured by customers,and not all parameters are considered 1 0 0 % complete.If there are any problems encountered during use on site,it is necessary to analyze the specific problems,use one's own experience,and adjust some helpful parameters to achieve the best use effect.

9.1Restore factory settings ( { H } 0 - 2 9 = 1 0 0 0 0 ,all other parameters excluding motor parameter group are restored to factory default values）Before performing industry application macro operations,please first execute:HO-29-10000

9.2 Constant pressure water supply application macro: (small tip: 1 \mathbf { b } \mathbf { a r } = 1 \mathbf { k } \mathbf { g } = 0 . 1 \mathbf { M } \mathbf { P } \mathbf { a } = 1 0 meters of water column)

Thecharacteristics of this constant pressure water supply:directly selecting the water supply macro,then inputing the sensor range value and self calibration pressure,other parameters can be basicallyunchanged to directly achieve efficient constant water supplycontrol.Thepressure regulationabilityis strong,theresponse is fast and sensitive,so itis beter than the traditional PID control frequency method for water supply control, with advantages such as stable pressure and more energy saving.At the same time,it has a bettr pressure maintenance effect on sites under pressure. Andthe motherboard dual relay can directly achieve one-to-three,or with the external relay control of Y1 and HDO terminals,it can achieve up to one-to-five water supply.It has independent pump and pump pressure reduction and delay control,and can also achieve dedicated time control for emergency pump reduction in case of over-pressure.As long as the time value of "bo-15 pressure upper limit emergency pump reduction delay" is appropriately reduced,the pump can be quickly reduced and stopped,avoiding the difficulty ofwaterpressure rising too quickly.

9.2.1 Single-pump variable frequency Hengle water supply macro:When HO-29-1,its automatic initialization parameters are as follows:(default panel potentiometer given target force and pressure value)

H0-01=2、H0- 0 2 = 1 、H0-03=8、H0- 1 4 = 2 0 . 0 0 { H z } \therefore { H } 4 - 1 8 = 2 . 0 0 , { H } 7 - 0 3 = 8 0 1 5 , { H } 7 - 0 4 - 0 0 0 1 { H } 7 - 0 5 = 3 0 0 3 、H7-17-15、H7 - 1 8 = 1 6 、HA . 0 0 = 3 、HA . 0 5 = 5 0 . 0 、HA . 0 6 = 0 . 1 0 、HA-28-0 (If the reactionrate isaccelerated,thevaluesofHA-05can be increasedand HA-06canbe decreased; Slow down the reaction speed, these two parameters are reversed),AI1 defaults to 0 ~ 1 0 { V } input as PID pressure feedback.If you need to change it to 4\~2oMA input,please supplement the parameters: 1 4 4 - 1 3 = 2 . 0 0 { V } ,H4-37-11 (set 1 as current input type).The default input of the frequency converter AI2 is 0 { - } 2 0 { m A } .IfAI2 is used as the PID pressure feedback source,the corresponding supplementary parameters are { H } 4 - 1 8 = 2 . 0 0 { V } and _ { { H } 4 - 3 7 } = 1 0 .When AHand AI2 are changed to current input,a 24V terminal needs to be connected in series as the sensor power supply.

The BO group is a constant pressure water supply parameter group,where 8O-oo is the range of thepressure sensor that needs to be inputtd truthfully.For example,if the maximum mark of the sensor is 1.6MP,then \underline { { \mathbf { B } 0 - 0 0 } } = 1 6 . 0 0 \mathbf {kg } . （204号

HA-0O is used to select the target pressure source.The default setting isa 3-key analog potentiometer.If 8 is selected,BO-01 will be set as the target pressure value for the water supply site. The default value is 5 . 0 0 {kg } ，which can be changed as needed.The pressure of late awakening and relateddelayscanbeadjusted.Thelatewake-uppressureandrelated delayparameters (including sleep,wake-up,and various pressure deviations)areallinked byatarget pressure percentage linkage mechanism,which canachieveadaptiveadjustment.Thesystemcanrun stablybydefault and usually doesnot require manual intervention.

9.5Application CasesofCNCLathes

Explanation

..The AI analog signal isa O-1oVvoltage signal

2.H0-10 and H0-12 are the maximum frequencies,which can be set according to actual system requirements;

3.Thedefault acceleration and deceleration time is1.5 seconds,and the shorter the time,the greater theimpact on the frequency converter.If there is no need to startand stop too quickly,the acceleration and deceleration time can be increased;

4.When using a frequency converter on a CNC lathe,a matching brake resistor must be installed;

5.If the shutdown over-voltage protection is applied,the value of H9-03 can be reduced.But the smaller this value,the greater the impact on IGBT;

6.If abnormal noise or insufficient torque is found in the motor,self-learning of the motor can be done.

9.6Motor parameter self-learning (tuning selection)

1.By self-learning the motor,the performance of the frequency converter and motor can be optimized, low-frequency torque can be increased,and abnormal overcurrent or overload protection can be avoided.

2.Inaddition,if thehighest frequency exceedsthe rated frequencyof { 5 0 } { { H z } } ,itisrecommended to do motor self-learning.

9.7Multi-speed Application Instructions

This series of products can setup to 16 operating frequencies and can be selected with a combination of _ 4 { ~ X ~ } terminal input signals.The relevant parameters for multi-segment instructions O to 15 are HC-0O to HC-15.The way inwhich multiple instruction segments Oare given is determined by the setting of parameter HC-51.

1.Set parameter HO-O3-6 and select the Multi-segment instruction as the main frequency.

2.Set the X terminal function selection,which can select X2,X3,X4,X5 (Hdl) as the signal input terminals for Multi-segment frequencycommands.Correspondingly,setH4-01,H4-02,H4-03,H4-04 to function values of 1 2 ~ 1 5 ，that is,specify the corresponding Multi-segment command input terminals 1 ~ 4 ：

HC-00\~HC-15 are the values set as the percentage of the highest frequency (HO-1O),such as { { H } } 0 - 1 0 = { 5 0 } { { H z } } ,HC-00-90;So,the frequency of the Multi-segment instruction O is 5 0 { { H z } } { x } 9 0 % = 4 5 { { H z } } Inthe above table, "ON" represents closed and "OFF" represents open.

ExampleofMulti-speedApplication

If external switch control isrequired for start stop,5 segments are needed, with the first segment being 1 0 { { H z } } ,the second segment being 3 0 { { H z } } ,the third segment being { \mathfrak { s o H z } } ,the fourth segment being 2 0 { { H z } } and the fifth segment being reversed by - 1 5 { H z } .Three segment terminalsare required. Set the following parameters:

1.Close SW1 and the frequency converter is running
2.Segment1:SW1,SW2,SW3 areall disconnected
3.Segment2:Disconnect SW2 and SW3 and closeSW1
4.Segment 3:Close SW2,disconnect SW1 and SW3
5.Segment 4: Close SW1 and SW2,disconnect SW3
6.Segment5:Close SW3,disconnect SW1 and Sw2

9.8 Acceleration and deceleration time setting

Acceleration time refers to the time required for the frequency converter to accelerate from 0 frequency to Ho-25 (acceleration/deceleration reference frequency).Deceleration time refers to the timerequired for the frequencyconverter to decelerate fromHO-25toO frequency(accelerationand deceleration reference frequency).

The frequency converter provides 4 sets of acceleration and deceleration times,and users can switch and select the four sets of acceleration and deceleration times through the digital input terminal { \Delta } _ { { X } } by setting the following parameters:

（Group 1）：H0-17、H0-18
（Group2）:H8-03、H8-04
（Group3）:H8-05、H8-06
（Group4）:H8-07、H8-08

Application examples

Taking X4 and HDI(X5) terminals as input switching terminals as an example,the detailed setup steps areasfollows.

2.By setting four sets of acceleration and deceleration time parameters,set the corresponding acceleration and deceleration time

Special note:If the deceleration time is tooshort,it willincrease the impacton the frequencyconverter, causing over-voltage or overcurrent protection.Optional responsive brake resistor can effectively avoid impact.

3.Set parameter Ho-19 (acceleration/deceleration time unit).When modifying this parameter,the decimal places displayed for the4sets of accelerationand deceleration timeswill change,and the corresponding acceleration and deceleration times will also change.Special attention should be paid during the application process.

4.Set parameter H6-07(acceleration and deceleration mode),select the acceleration and deceleration modeof the frequency converter,thatis,select the frequency change mode of the frequencyconverter during the start and stop process.

O:The output frequency increasesordecreases linearly 1:When the target frequency is fixed,the output frequency increases or decreases according to the S-curve (detailed setings need to be made through H6-08 and H6-09).Suitable for use in places that require gentle starting or stopping,such as elevators,conveyor belts,etc. 5.Set parameters H6-08and H6-O9,and setthe time ratio for the startand end periods of the S-curve. At the same time,the parameters H6-08 and H6-O9 are required to be fully set: _ { { H 6 - 0 8 ~ + ~ } } （204号 { { H } } 6 { * } 0 9 { <= } 1 0 0 . 0 % ：

9.9 TimerFunction

The frequency converter starts counting from O every time it is started,and automaticall stops when the scheduled running time (H8-44) is reached.The remaining running time of the timer can be viewed through UO-20 or through digital display2 (set { H } 7 - 1 8 = 2 0 )

When the cumulative power on time (H7-13） of the frequency converter exceeds the set cumulative power onarrival time (H8-16),the DO terminal outputsa valid signal.

When the cumulative operating time of the frequency converter (H7-O9）exceeds the set cumulative operating arrival time (H8-17),the D0 terminal outputs a valid signal. Related parameters

9.11Precautionsforuse

1.What shouldIdo if the motor reverses?

If the motor is installed with a frequency converter and reverses,it can be solved by replacing the motor phase sequence.First,disconnect the power supply of the frequency converter.When the frequency converter panel and power indicator light are completely off,replace the two motor wires U and Wat the output terminals of the frequency converter.Generally,this can solve the problem of motor reversal.

2.Can one frequency converter drive multiple motors?

If multiple motors are running synchronously,starting and stopping simultaneouslyat the same speed.Can be driven by a frequency converter.The selected frequency converter power needs to be greater than1.5 times the total power of all motors.Inaddition,theprotection of the frequency converterwillfail,and it is necessry to install protective devices suchasthermal relays foreach motor.

If multiple motors are not running synchronously,each motor needs to be separately equipped witha frequency converter.

3.Can the output terminal of the frequency converter be connected to a contactor?

Normally,it is not allowed to connect a contactor to the output terminal of a frequency converter. This is because when the contactor at the output terminal of the frequency converter is not engaged, andthe frequency converter is started and reachesacertain frequencybefore thecontactor is engaged, a largeoverload current will occur,causing the frequency converter to trip due to overcurrent or damage the frequency converter.

If a contactor must be connected to the output terminal of the frequency converter during use,the control circuit must ensure that the output contactor is engaged before the frequency converter starts.

It is not allowed to use the output contactor of the frequency converter as a stop or start component.Do not connect the motor to a running frequency converter output system.

Prohibit starting running motor equipment (unless frequency tracking start is se

4.How to maintain a frequency converter that has been stored for a long time?

Asan electronic product, frequency converters require regular charging and discharging of electrolytic capacitors with larger internal capacity.If the frequency converter is not used for a long time,it needs to be powered on for10 minutes every six months.

5.Precautions for frequency converters with fans

Asone of the most common devices in variable frequency control systems,wind turbine loads need to pay attention to the following points:

The deceleration time should not be too short,with different powers,and the factory deceleration time should be increased as much as possible.

Do not use the "free parking"and "automatic reset" functions unless you have set the "speed tracking"function.

If the "speed tracking" function is notset,the frequencyconverter cannot be started while the fan is still inertia rotating.

If the air volume is still not as high as the power frequency after installing the frequency converterat { \mathfrak { s o H z } } ,the slip compensation can be increased and the value ofH3-O9 can be set. 6.How to extend the service life of frequency converters?

As an electronic product, frequency converters are most afraid of severe moisture,oil mist, dust, iron filings,high temperatures,etc.in the usage environment.If the installation and use environment is poor,itwill seriously affect the service life of the frequency converter.

Install the frequency converter inside the control cabinet and ensure proper dust prevention and heat dissipation.Theair duct of the control cabinet enters and exits from below,with a dust cover installed at the inlet andacooling fan installedat the outlet to draw air outward.Ensure good ventilation and install one or more inlet and outlet fans according to actual needs.
