Description
Possible reason
corrective-measures
Overvoltage at
constant speed
1. Abnormal changes in input voltage.
2. The load inertia is large.
1. Install input reactor.
2. Plus suitable energy
consumption brake components.
BUS
undervoltage
1. The input power supply voltage is low.
2. Instant power outage.
3. The circuit board is abnormal.
1. Check the input power
2. Reset fault
3. Seek service
Inverter overload
1. Accelerate too fast.
2. Restart the rotating motor.
3. The input power voltage is too low.
4. The load is too large.
1. Increase the acceleration time.
2. Avoid restarting after
shutdown.
3. Check the input power voltage
4. Select the inverter with higher
power.
Motor overload
1. The input power voltage is too low.
2. The motor rated current is set
incorrectly.
3. The motor is blocked or the load
mutation is too large.
4. Motor overloaded.
1. Check the input power voltage.
2. Reset the rated current of the
motor.
3. Check the load and adjust the
torque boost.
4. Choose the right motor.
Motor overload 2
1. The motor is blocked or the load is too
large.
2. Improper setting of protection
parameters.
1. Check the load.
2. Set appropriate protection
parameters.
Input phase loss R/L1,S/L2,T/L3 Input phase loss
1. Check the input power.
2. Check the installation wiring.
Output phase
loss
U/T1,V/T2,W/T3 phase loss on output
side (or the load three-phase is severely
asymmetric)
1. Check the output wiring.
2. Check the motor and cable
Module overheat
1. Inverter overcurrent instantly.
2. The output three phases have
interphase or ground short circuit.
3. The air duct is blocked or the fan is
damaged.
4. The ambient temperature is too high.
5. Loose connection of control board or
plug-in.
6. The auxiliary power supply is
damaged, and the driving voltage is
undervoltage.
7. Power module bridge arm is straight
through.
8. The control board is abnormal.
1. See overcurrent
countermeasures.
2. Rewiring.
3. Ventilate channels or replace
fans.
4. Reduce the ambient
temperature.
5. Check and reconnect.
6. Seek service.
7. Seek service.
8. Seek service.
External fault
MI external fault input terminal action
Check external device input
Communication
error
1. The baud rate is not set properly.
2. Communication error using serial
communication.
3. Communication is interrupted for a
long time.
1. Set the appropriate baud rate.
2. Press STOP/RESET button to
reset and seek service.
3. Check the wiring of the
communication interface.
