Fault
code
Fault categories
Possible reasons of fault
Actions
The drive's and motor's power not
matched with each other
Use suitable motor
E012 Drive
over-load
Too short Acc time
Prolong the Acc time
The rotating motor re-start
Avoid re-start after the drive stops
instantly
Low AC supply voltage
Check the AC supply voltage
Too heavy load
Select a high power drive
E013 Input phase loss
Any of phase R, S and T cannot be
detected
Check the input power supply
Check the drive’s output wiring
E014
Output phase
failure
U, V, W output loss (or the 3-phase
loads are serious asymmetry)
Check the drive’s output wiring
Check the cable and the motor
E015
Terminal input
lack water
The Lack water terminal input
signal is valid
Check for water shortages
Check input terminal signals
E016
IGBT module’s
heatsink
overheat
Vent is obstructed or fan does not
work
Clean the vent or replace the fan
Over-temperature
Lower the ambient temperature
Wires or connectors of control
board are loose
Check and rewiring
Auxiliary power supply is damaged
or IGBT driving voltage is too low
Seek service
Short-circuit of IGBT bridge
Seek service
Control board is abnormal
Seek service
E017
External
equipment fails
Terminal SI used for inputting
external faults acts
Check the input of the external device
E018
RS485
communication
failure
Wrong baud rate setting
Set the baud rate correctly
Serial port communication error
Press STOP/RST to reset, Seek service
Communication break for long
time
Check the wiring of serial port
E019
Current
detection circuit
has fault
Wires or connectors of control
board are loose
Check and re-wire
Auxiliary power supply is damaged Seek service
Hall sensor is damaged
Seek service
Amplifying circuit is abnormal
Seek service
E020
Auto-learning
fails
Motor's and drive's capacity doesn't
match each other.
Replace the drive with another model
Improper settings of parameters on
the nameplate
Set the parameters correctly according to
the nameplate
Auto-learned and standard
parameters have large deviations
Let the motor no load, re-identify
