without driving it.

- Motor internal connections
- Motor power cables connections
- Motor leakage to truck frame
- If the motor connections are OK, the problem is inside the controller

Troubleshooting:
Please check
- The motor connected to –P must be completely still before this alarm
occours. The software waits 30 seconds before showing this alarm. During
this time it shows the “WAIT MOTOR STILL” warning (see in the warnings
chapter)
- Motor internal connections
