Remedy: Re fault cause = 0:
If required, deactivate an active internal voltage protection (p1231).
Re fault cause = 1:
Update the Control Unit firmware or change the DRIVE-CLiQ topology.
Re fault cause = 2:
Replace the power unit with a PM260 with PS-ASIC version 3 (or higher).
Re fault cause = 3, 4:
Insert a Control Unit or Control Unit Adapter (CUAxx) on an appropriate Power Module and perform a POWER ON
for the Control Unit or the Control Units Adapter.
Re fault cause = 5:
- use a booksize format power unit.
- for a Double Motor Module operate the two drive controls with the same current controller sampling time (p0115[0]).
Otherwise, the higher current controller dynamics can only be activated on the drive with the longer sampling time.
- If required, de-select the higher current controller dynamic performance (p1810.11 = 0). After deselecting the com-
puting dead time, recalculate the controller gains (p0340 = 4). If required, optimize the speed controller.

F30021 Power unit: Ground fault
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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, decimal interpretation):
Absolute value, total current amplitude [20479 = r0209 x 1.4142].
Note:
For power units, a ground fault is also emulated in r3113.5.
Remedy: - check the power cable connections.
- check the motor.
- check the CT.
The following applies additionally for CU310/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).

F30022 Power unit: Monitoring U_ce
Message value: Fault cause: %1 bin
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2
Acknowledge: POWER ON
Cause: In the power unit, the monitoring of the collector-emitter voltage (U_ce) of the semiconductor has responded.
Possible causes:
- fiber-optic cable interrupted.
- power supply of the IGBT gating module missing.
- short-circuit at the power unit output.
- defective semiconductor in the power unit.
Fault value (r0949, interpret binary):
Bit 0: Short-circuit in phase U
Bit 1: Short circuit in phase V
Bit 2: Short-circuit in phase W
