Possible causes of failures, fault diagnosis, and measures to be taken
F0001
Overcurrent
? The power of the motor does not correspond to the power of the inverter
? Wire short circuit of the motor
? Have ground fault check the following items
1. The power of the motor P0307 must be the power of the inverter P0206
Corresponding
2. The length of the cable must not exceed the maximum allowed
3. There must be no short circuit or ground fault in the cable and motor of the motor.
4. The motor parameters of the input inverter must correspond to the actual motor parameters used.
5. Enter the inverter's stator resistance value P0350 must be correct
6. The cooling air duct of the motor must be unobstructed and the motor must not be overloaded.
? Increase the ramp time
? Reduce the value of the increase

F0002
Overvoltage
? The voltage of the DC link r0026 exceeds the trip level P2172
? Overvoltage due to excessive supply voltage or motor in regenerative braking mode
? The slope drops too fast or the motor is rotated by a large inertia load and is under regenerative braking. Check the following items.
1. The power supply voltage P0210 must be within the range specified on the inverter nameplate.
2. The DC link voltage controller must be valid P1240 and correctly parameterized
3. The ramp-down time P1121 must match the inertia of the load

F0003
Undervoltage
? Power supply failure
? The impact load exceeds the specified limit value. Check the following items.
1. The power supply voltage P0210 must be within the range specified on the inverter nameplate.
2. Check if the power supply is short-circuited or there is a transient voltage drop.
Off2
F0004
Inverter over temperature
? Cooling fan failure
? The ambient temperature is too high Check the following items
1. The cooling fan must be running normally when the inverter is running.
2. The frequency of the modulation pulse must be set to the default value.
3. The inlet and outlet of the cooling duct must not be blocked. The ambient temperature may be higher than the allowable value of the inverter.
Off2
F0005
Inverter I2 t over temperature
? Inverter overload
? Work/stop gap cycle time does not meet the requirements
? Motor power P0307 exceeds the load capacity of the inverter P0206
