F30072

Setpoints can no longer be transferred to the Power Module

Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: More than one setpoint telegram was not able to be transferred to the power unit module.
Remedy: Check the interface (adjustment and locking) to the power unit module.
F30074 (A)

Communication error between the Control Unit and Power Module

Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: Communications between the Control Unit (CU) and Power Module (PM) via the interface no longer possible. The CU may
have been withdrawn or is incorrectly inserted.
Fault value (r0949, interpret hexadecimal):
0 hex:
- a Control Unit with external 24 V supply was withdrawn from the Power Module during operation.
- with the Power Module switched off, the external 24 V supply for the Control Unit was interrupted for some time.
1 hex:
The Control Unit was withdrawn from the Power Module during operation, although the encoderless safe motion
monitoring functions are enabled. This is not supported. After re-inserting the Control Unit in operation, communications
to the Power Module no longer possible.
20A hex:
The Control Unit was inserted on a Power Module, which has another code number.
20B hex:
The Control Unit was inserted on a Power Module, which although it has the same code number, has a different serial
number. The Control Unit executes an automatic warm restart to accept the new calibration data.
Remedy: For fault value = 0 and 20A hex:
Insert the Control Unit on an appropriate Power Module and continue operation. If required, carry out a POWER ON of the
Control Unit.
For fault value = 1 hex:
Carry out a POWER ON of the Control Unit.
F30075

Configuration of the power unit unsuccessful

Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A communication error has occurred while configuring the power unit using the Control Unit. The cause is not clear.
Fault value (r0949, interpret decimal):
0:
The output filter initialization was unsuccessful.
1:
Activation/deactivation of the regenerative feedback functionality was unsuccessful.
Remedy: - acknowledge the fault and continue operation.
- if the fault reoccurs, carry out a POWER ON (switch-off/switch-on).
- if required, replace the power unit.
F30080

Power unit: Current increasing too quickly

Reaction: OFF2
