230021 <location>Power unit: Ground fault
Message
value:
%1
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Power unit has detected a ground fault.
- ground fault in the power cables
- winding fault or ground fault at the motor.
- CT defective.
Additional cause for CU310/CUA31:
- when the brake is applied, this causes the hardware DC current monitoring to respond.
Additional cause for parallel switching devices (r0108.15 = 1):
- the closed-loop circulating current control is either too slow or has been set too fast.
Fault value (r0949, interpret decimal):
Absolute value, summation current [32767 = 271 % rated current].
Remedy: - check the power cable connections.
- check the motor.
- check the CT.
The following applies additionally for CU310 and CUA31:
- check the cables and contacts of the brake connection (a wire is possibly broken).
For parallel switching devices (r0108.15 = 1) the following additionally applies:
- check the ground fault monitoring thresholds (p0287).
- check the setting of the closed-loop circulating current control (p7036, p7037).
