F30039 Power unit: Failure capacitor fan
Drive object: B_INF
Reaction: OFF1
Acknowledge: IMMEDIATELY
Cause: The capacitor fan has failed.
Remedy: Replace the capacitor fan in the power unit.
F30040 Power unit: Undervolt 24 V
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: Failure of the 24 V power supply for the power unit.
- the 16 V threshold was fallen below for longer than 3 ms.
Fault value (r0949):
24 V voltage [1 bit = 0.1 V].
Remedy: Check the 24 V DC voltage supply to power unit.
A30041 (F) Power unit: Undervoltage 24 V alarm
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: 24 V power supply fault for the power unit.
- the 16 V threshold was fallen below.
Fault value (r0949):
24 V voltage [1 bit = 0.1 V].
Remedy: Check the 24 V DC voltage supply to power unit.
Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE (OFF1, OFF2, OFF3)
VECTOR: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A30042 Power unit: Fan operating time reached or exceeded
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The maximum operating time of the fan in the power unit is set in p0252.
This message indicates the following:
Fault value (r0949, interpret decimal):
0: The maximum fan operating time is 500 hours.
1: The maximum fan operating time has been exceeded.
Remedy: Replace the fan in the power unit and reset the operating hours counter to 0 (p0251 = 0).

F30043 Power unit: Overvolt 24 V
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: The following applies for CU31x:
Overvoltage of the 24 V power supply for the power unit.
- the 31.5 V threshold was exceeded for more than 3 ms.
Fault value (r0949):
24 V voltage [1 bit = 0.1 V].
Remedy: Check the 24 V DC voltage supply to power unit.
