Voltage saturation
1. Check whether there is an open circuit among the motor connection cables,
please connect the motor cables correctly if there is an error.
2. Check whether the input motor nameplate parameters are correct, please
correct if there is a mistake.
3. Shorten the motor power cable length (<1000m) or increase the motor power
cable diameter.
15
Too high rotor resistance value
1. Check whether the input motor nameplate parameters are correct, please
correct the mistakes.
2. Shorten the motor power cable length (<1000m) or increase the motor power
cable diameter.
16
Excessive inductance
1. Check whether the input motor nameplate parameters are correct, please
correct the mistakes.
2. Shorten the motor power cable length (<1000m) or increase the motor power
cable diameter.
40
Self-learning timeout
1. Check whether the input motor nameplate parameters are correct, please
correct if there is a mistake.
2. Check whether the difference between inverter power level and motor power
level is too large (>3 levels).
3. If the fault is not eliminated after several times of self-learning, please contact
the manufacturer.
41
Parameter error
Re-enter the motor nameplate parameters correctly and make sure the rated
frequency of the motor is in the range of 10~500Hz.
44
Negative rotor resistance
1. Check whether the input motor nameplate parameters are correct.
2. If the fault is not eliminated after several times of self-learning, please contact
the manufacturer.
45
Synchronous motor output voltage
exceeds limit
Check whether the input motor nameplate parameters are correct (especially
whether the keyboard input rated frequency is larger than the motor nameplate
rating).
46
High learning counter potential voltage
Check whether the input motor nameplate parameters are correct (especially
whether the keyboard input rated frequency is larger than the motor nameplate
rating).
47
Low learning counter potential voltage
1. Check whether the input motor nameplate parameters are correct (especially
