6.2.1 Pump control area function description
1：Control mode
Set the pump control mode.
2：Operation Mode
To further improve the energy saving effect function.Normal operation is to use one driver as the main controller and
only one pump in PID control variable frequency mode. The average distribution operation mode is an operation mode
in which all linked pumps distribute the total output rate to all linked pumps according to the PID control method. The
average distribution mode operation function can only be used when the diameters of the system pipes are the same,
and it has the advantage of preventing the main driver from running continuously for a long time.
3：Mode Switching
Pump changing sequence in linkage operation.
4：Pump Adding Delay
Specially refers to the function of delaying the adding of pumps when the standby pump is in linkage
operation. It is a preventive measure to prevent the high pressure event caused by the operation pressure
lag and the standby pump operate when a pump reaches the maximum output frequency.
G2-14: Forced standby timing
If the forced alternation time is set to 0,
the pump changing mode will be invalid.

10：Minimum frequency percentage
ㆍThe minimum output frequency of the drive when it stops.
Note: The minimum output frequency must be less than the start output frequency.
ㆍSensing low flow. If the output frequency% is lower than the energy-saving frequency%, it is considered a low flow state.
ㆍExample: After the operating pressure reaches the set pressure, the output frequency is lower than the energy-saving
frequency% and is considered a low flow.
ㆍSensing low flow, if the output current is lower than the energy-saving current, it is considered a low flow state.
ㆍExample: After the operating pressure reaches the set pressure, the output current is lower than the energy-saving
current, which is considered a low flow.
ㆍCurrent Pressure＜pressure setting value-The pump starts running when the pressure deviation value is set.
ㆍCurrent Pressure≥pressure setting value-The pump starts to stop at the set pressure deviation value.
ㆍThe initial output frequency of the driver when it starts.
Note: The startup output frequency must be greater than the minimum output frequency.
ㆍDelay deceleration and shutdown conditions which are met energy-saving frequency/energy-saving power.

Er-28：Abnormal CAN_BPS setting
Cause:
ㆍCAN communication speed setting is abnormal.
Measure:
ㆍThe CAN communication speed setting is abnormal. Modify the communication speed and clear the
fault after the network is connected.
Er-29：Current sensor failure
Cause:
ㆍThe current sensor triggers an alarm when the output is abnormal.
Measure:
ㆍWhether the power failure restart is lifted or not.
ㆍConsult the operation and maintenance service department.
