CDE360 Vector Control AC Drive

7.2 Common Faults and Solutions

You may come across the following faults during the use of the drive. Refer to the following
methods for simple fault analysis.
There is no display at power-on:
1) Check whether the drive input power voltage is consistent with drive rated voltage.
2) Check whether the Three phase bridge rectifier is normal.
Power air switch tripping at power-on
1) Check whether the motor or the motor cable is short circuited to the ground.
2) Check whether rectifier bridge is damage.
Motor not rotate when drive is running.
1) Check whether the output current of U, V, W are in unbalance status.
2) Check whether the motor is damage or stalling.
3) Check whether the motor parameters set proper value.
The display is normally at power-on but the power air switch tripping when the drive run.
1) Check whether the output module is short circuited to the ground.
2) Check whether the motor is short circuited to the ground.
3) If the power air switch tripped occasionally and between the motor with drive have long
distance, then add AC reactor please.
Note:
 Please deal with the fault carefully. You should confirm the fault reasons and deal with the
fault according to solutions above.
 If you can't solute the fault, please don't power on.
 If the device damaged or some problem you can't solute, please contact with distributor or
technical service.
