4.2 List of faults and alarms
F30040 Power unit: Undervolt 24 V
Message value: %1
Message class: Supply voltage fault (undervoltage) (3)
Drive object: VECTOR_G
Component: Power Module Propagation: LOCAL
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The undervoltage threshold of the 24 V power supply for the power unit was fallen below for longer than 3 ms.
Note:
- for booksize power units, the undervoltage threshold is 15 V.
- for CU310-2, CUA31 and CUA32 the undervoltage threshold is 16 V.
- for all other power units, the undervoltage threshold depends on the power unit, and is not displayed.
Fault value (r0949, interpret decimal):
24 V voltage [0.1 V].
Remedy: - check the power supply of the power unit.
- carry out a POWER ON (switch-off/switch-on) for the component.
F30040 Power unit: Undervolt 24 V
Message value: %1
Message class: Supply voltage fault (undervoltage) (3)
Drive object: B_INF
Component: Power Module Propagation: LOCAL
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The undervoltage threshold of the 24 V power supply for the power unit was fallen below for longer than 3 ms.
Note:
- for booksize power units, the undervoltage threshold is 15 V.
- for all other power units, the undervoltage threshold depends on the power unit, and is not displayed.
Fault value (r0949, interpret decimal):
24 V voltage [0.1 V].
Remedy: - check the power supply of the power unit.
- carry out a POWER ON (switch-off/switch-on) for the component.
A30041 (F) Power unit: Undervoltage 24 V alarm
Message value: %1
Message class: Supply voltage fault (undervoltage) (3)
Drive object: VECTOR_G
Component: Power Module Propagation: LOCAL
Reaction: NONE
Acknowledge: NONE
Cause: For the power unit power supply, the lower threshold has been violated.
Alarm value (r2124, interpret decimal):
24 V voltage [0.1 V].
Remedy: - check the power supply of the power unit.
- carry out a POWER ON (switch-off/switch-on) for the component.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
