fault
Possible reasons of fault
Instantaneous over-current
Short-circuit among 3-phase output or
line-to-ground short circuit
Vent is obstructed or fan does not work
Over-temperature
Wires or connectors of control board are loose
Current waveform distorted due to output
phase loss
Auxiliary power supply is damaged or IGBT
driving voltage is too low
Short-circuit of IGBT bridge
Control board is abnormal
Over-temperature
Vent obstructed
Fan does not work
IGBT module is abnormal
Ambient over-temperature
Obstruction of ventilation channel
Fan does not work
Too short Acc/Dec time
DC injection braking current is too big
Improper V/F curve
The rotating motor restart after the drive stops
instantly.
Low AC supply voltage
Too heavy load
Improper V/F curve
Low AC supply voltage
Common motor has operated with heavy load
at low speed for a long time.
Improper motor's overload protection threshold Modify the motor's overload protection
Load changes fast
STOP is pressed in non-panel control mode
STOP pressed when the drive is in stall status
The drive will report E015 fault if it is in stall
status for 1 minute
Terminal used for stopping the drive in
emergent status is closed

Lower the ambient temperature
Clear the ventilation channel
Replace the fan
Prolong the Acc/Dec time
Reduce the DC injection braking current
or prolong the braking time
Adjust V/F curve or torque boost value
Set the starting mode (F2.00) to "start of
fly"
Check the AC supply voltage
Select the drive with bigger power
Set V/F curve and torque boost value
correctly
Check the AC supply voltage
Use a special motor if the motor is
required to operate for a long time.

Check the load
Check the definition of STOP function in
F9.07 and the operating mode
Check the definition of STOP function in
