  • Check drive ratio.

  • Increase inverter’s capacity.
6: L.U.
Under-Voltage Protection
Cause: Input voltage on the low side.



Remedy:

  • Check if supply voltage is normal.

  • Check if parameter setting is correct.
7: O.H.
Radiator Overheat
Cause:
Environment temperature too high; radiator too dirty; install place not good for ventilation; fan damaged; Carrier wave frequency or compensation curve is too high.



Remedy:

  • Improve ventilation.

  • Clean air inlet, outlet, and radiator.

  • Install as required.

11: ESP
External fault
Cause: External emergency-stop terminal is valid.



Remedy:

  • Check external fault.
12: Err3
Current malfunction before running
Cause: Current alarm signal exists before running.



Remedy:

  • Check if control board is connected with power board well.

  • Ask for help from manufacturer.
13: Err2
Parameters tuning wrong
Cause: Do not connect motor when measuring parameters.



Remedy:

  • Please connect motor correctly.
15: Err4
Current zero excursion malfunction
Cause: Flat cable is loosened; Current detector is broken.



Remedy:

  • Check the flat cable.

  • Ask for help from manufacturer.
17: PF0
Output Phase loss
Cause: Motor is broken; Motor wire is loose; Inverter is broken.



Remedy:

  • Check if wire of motor is loose.

  • Check if motor is broken.
18: AErr
Line disconnected
Cause: Analog signal line disconnected; Signal source is broken.



Remedy:

  • Change the signal line.

  • Change the signal source.
19: EP3
20: EP/EP2
Inverter under-load
Cause: Water pump dries up; Belt is broken; Equipment is broken.



Remedy:

  • Supply water for pump.

  • Change the belt.

  • Repair the equipment.
22: nP
Pressure control
Cause: Pressure is too high when negative feedback; Pressure is too low when positive feedback; Inverter enters into the dormancy status.



Remedy:

  • Decrease the min frequency of PID.

  • Reset inverter to normal status.
23: Err5
PID parameters are set wrong
Cause: PID parameters are set wrong.



Remedy:

  • Set the parameters correctly.
26: GP
Earth fault protection
Cause: Motor cable is damaged, short connected to grounding; Motor isolation is damaged, short connected to grounding; Inverter fault.



Remedy:

  • Change a new cable.

  • Repair the motor.

  • Contact manufacturer.
27: GP
Encoder fault
Cause: Encoder installation error; Encoder fault; Encoder line number fault.



Remedy:

  • Check the installation and connection.

  • Check encoder.

  • Set F851 correctly.
32: PCE
PMSM distuning fault
Cause: Motor parameters measurement is wrong; Load is too heavy.



Remedy:

  • Measure motor parameters correctly.

  • Decrease the load.
