Fault Checking & Troubleshooting

5.1 Fault Alarm & Troubleshooting

The PH300 series servo drive provides alarm information and protective functions. When

a fault occurs, PH300 serie servo drives implement the protective function, stop output, makes

the fault relay act, and displays the fault code on the operation panel. Before contacting Physis

for technical support, you can first determine the fault type, analyze the causes, and perform

troubleshooting according to the description in this chapter. If the fault can’t be rectified, please

contact the agent or Physis.

The OUOC in the warning message is a hardware overcurrent or overvoltage signal. In

most cases, the hardware overvoltage fault causes the OUOC alarm.

Symptom Fault Display Possible Causes Solutions

Selection of Peripheral Electrical Devices Applied Braking resistor Specification

Calculate of Braking resistor value:

The braking resistor value is related to braking torque Mbr％ , and for the different braking

torque, the braking resistor values are different.

The calculation formula is as follows:

Udc——DC voltage of brake ；PMotor ——Motor power ；Mbr——Braking torque ；

ηMotor ——Motor efficiency ；η Driver ——Drive efficiency 。

The braking power is related to braking torque and braking frequency, as the calculation

formula above indicates the braking torque is 125% , the frequency is 10%. However, according

to the different load, the values in the calculation formula are just for reference only.

Multi-pump Control of IMM

Due to the limit of motor power and pump displacement, single pump can’t meet the

requirements of displacement, large tonnage injection molding machine needs multi-pump in

parallel to converge maximum flow.

The parallel pump control is classified into multi-pump convergent flow and multi pump

distributed flow.

Multi-pump convergent flow：A servo motor is used as the master drive, and the other

drives are used as slave drives connected in parallel. The host computer outputs a set of flow

and pressure analog signals.

Multi pump distributed flow：Multiple servo drives may work in multi-pump convergent flow

mode or multi pump distributed flow mode (distributed PID control based on the oil pressure).

The host computer outputs multiple sets of flow and pressure analog signals.

0 Multi-pump 1 (broadcast mode)

1 Multi-pump 2 (multi-master mode)

Multi-pump 1:

● This mode is broadcast mode and is applicable to simple multi-pump control.

● When the slave pump is switched over to the master pump, the slave pump can’t be

controlled.

● To enable the multi-pump mode, set the DI terminal for 50# function.

● After disconnecting the DI terminal set for 50# function of the slave pump, the slave pump is

switched over to the master pump.

Multi-pump 2 :

◆ Wiring（Multi-pump convergent flow）

This mode is the multi-master mode and can satisfy more complicated multipump convergent and distributed flow control. It supports a maximum of 4 multi-pump

distributed flow control combinations.

Multi-pump distributed flow:

Set the corresponding parameter in group P6.02=25 (slave alarm output) and connect this

signal to the system computer for alarm display.

Set the corresponding parameter in group P6.02=25 (slave alarm output) and connect this

signal to the system computer for alarm display.

Note: High-pressure without cause occurs on the oil channel of the slave pump in the

pressure control when leakage of the check valve is large while the inner discharge of the

slave pump is small. To relieve the high-pressure state of the oil channel, do as follows:

Reduce the discharge of the slave pump to reasonable range.

Decrease the torque upper limit of the slave drive to reasonable range.

Set the speed response curve according to the max. discharge speed of the master

pump, ensuring that the slave drive implements automatic pressure relief t low-speed

holding pressure. For detailed parameter setting, refer to the following “ Parameter Setting

for Slave Pump Response to Master Pump Reference” part.

Multi–pump Control Mode Selection of Peripheral Electrical Devices

79

Note : The two multi-pump modes have the same parameter setting for the slave pump response to the

master pump speed reference.

For example:

Condition 1 : Suppose the max. pressure holding speed of the master is 50 rpm/min, the max.

speed of the master is 2000 rpm/min.

Condition 2: At pressure holding, the master works and the slave stops.

Condition 3: To ensure flow linearity, the master is over 100 rpm/min., and the slave keeps the

same speed.

When the mater group is below 50 rpm/min., the slave pump stops running. When the master

pump is above 100 rpm/min, the master pump and the slave pump keep the same speed.

The speed reference of the master pump is 0% to 100%. You can set PC.10 to PC.15 to get the

three-point curve to make the slave pump respond to the speed reference as follows:

( PC.10, PC11 ) = Slave pump input reference: 50 rpm/min., slave response reference: 0 rpm/

min. = 2.5%, 0.0%

( PC.12, PC13 ) = Slave pump input reference: 100 rpm/min., slave response reference: 100

rpm/min. = 5.0%, 5.0%

( PC.14, PC15 ) = Slave pump input reference: 2000 rpm/min., slave response reference: 2000

The parameter setting is simple. For all servo drives, allocate a X terminal and set the

parameter to 50.

The servo drive with address 1 must be the master pump. A maximum of four combined

distributed flow control can be implemented. The related parameter settings are as follows:

●　 Bit0 corresponds to the slave pump station No.1, Bit1 corresponds to station No.2, by

that analogy, Bit14 corresponds to station No.15.

●　 When address station number is 1, it indicates that the slave pump of the address

station No.

●　 The PH300 series servo drives support the setting of a total 15 slave pump addresses.

For example, 1# is the master pump, Pd.10=1x2¹+1x2²+1x2³=14, indicating that 1# is the

master pump, and works with slave pumps 2#, 3# and 4#.

8.5 Applications of Multi-pump Convergent and Distributed

Flow Control

◆ Multi-pump Mode 1 (Pd.09 = 0)

For example, the IMM servo pump system consists of the three pumps with the address set

as 1#, 2# and 3#. In the multi-pump mode 1, when a slave pump is used as the master pump,

the slave pump doesn’t follow its speed.

And there are the following 2 combinations:

●　 Combination 1: 3-pump convergent flow

●　 Combination 2: 2+1 combination for distributed flow control

The following describes the wiring and setting of the above two combinations:

Note:

The 1# master pump is followed by the 2# slave pump, and you can switch over the 3#

pump to the master pump by disconnect the X terminal set for the 50# function of the slave

pump.

Note:

Because the 1# pump is always the master pump and the 2# pump always the slave pump,

directly short the X terminal set for 50# function.

The 3# pump switches over to the master pump in the following combination 2, which

requires an external switches signal. When the host computer sends the closing signal, the X

terminal set for the 50# function of the slave pump closes to process the multi-pump convergent

flow.

■  Combination 2: 2+1 combination for distributed flow control

84 The 1# master pump is followed by the 2# slave pump, and the 3# pump switches over to the master

pump.

◆ Multi-pump Mode 2 (Pd.09 = 1)

For example, the IMM servo pump system consists of four pumps with the address set as

1#, 2#, 3# and 4#.

● Combination 2: 2+2 combination for distributed flow control

● Combination 3: 3+1 combination for distributed flow control

Note:

The convergent flow control requires very simple wiring including CAN bus and X terminal

wiring.

The 1# pump is the master pump, and the 2#, 3# and 4# pumps are slave pumps. The

setting of address of corresponding slave pumps is Pd.10=1x2¹+1x2²+1x2³=14.

■  Combination 2: 2+2 combination for distributed flow control

86 Note:

The host computer provides the distributed flow signal. Connect the distributed flow signal

to the X terminal set for the 53# function of the master drive. The master pump identifies the

salve pump address through the 53# X signal. The slave pump switches over to the master

pump and identifies the slave pump address by using the 53# X signal.

In this combination, the 1# pump and 3# pump are the master pump. The slave pump

changes and the address of the salve pump needs to be set. The slave pump of the 1# master

pump is 2# pump, the setting of address of 1# master pump is Pd.11=1x21=2. The slave pump

of the 3# master pump is 4# pump, the setting of address of 3# master pump is Pd.11=1x23=8.

The 1# master pump is followed by the 2# slave pump, and the 3# pump works as the

master pump which is followed by the 4# slave pump.

Note:

The host computer provides the distributed flow signal. Connect the distributed flow signal

to the X terminal set for the 54# function of the master drive. The master pump identifies the

salve pump address through the 54# X signal. The slave pump switches over to the master

pump and identifies the slave pump address by using the 54# X signal.

Disconnect the X terminal set for the 53# function in the second combination.

In this combination, the 1# pump and 4# pump are the master pump. The slave pump

changes and the address of the salve pump needs to be set. The slave pump of the 1# master

pump are 2# pump and 3# pump, the setting of address of 1# master pump is Pd.12=1x21

+1x22=6. After the 4# slave pump switches over to the master pump, no slave pump follows it,

therefore, Pd.11 doesn’t need to be set, that is Pd.11=0.

■  Combination 3: 3+1 combination for distributed flow control

The 1# master pump is followed by the 3# and 4# slave pumps, and the 2# slave pump

switches over to the master pump.
