| Question | Reason | Solution |
|---|---|---|
| Servo trip | There is a short circuit between U, V and W phases inside the motor. | Use multimeter to detect the resistance values between the motor UV, UW, and VW (For cable pin define u could check here). Normally, the three-phase resistance should be equal. If it is less than 1 ohm, it means a short circuit between the phases. |
| There is a short circuit between U, V, W and ground (PE). | Use multimeter to detect the resistance values between U&PE, V&PE, and W&PE of the motor (For cable pin define u could check here). If the resistance value is not infinite, it can be confirmed that U, V, and W inside the motor are short-circuited to ground (PE). |
