A30044 (F) Power unit: Overvoltage 24 V alarm
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The following applies for CU31x:
24 V power supply fault for the power unit.
- the 32.0 V threshold was exceeded.
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)
F30045 Power unit: Supply undervoltage
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: The following applies for CU31x:
Power supply fault in the power unit.
- the voltage monitoring on the DAC board signals an undervoltage fault on the module.
Remedy: Check the 24 V DC power supply for the power unit and if required replace the module.
A30046 (F) Power unit: Undervoltage, alarm
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: Before the last new start, a problem occurred at the power unit power supply.
- the voltage monitoring in the internal FPGA of the PSA signals an undervoltage fault on the module.
Fault value (r0949):
Register value of the voltage fault register.
Remedy: Check the 24 V DC power supply for the power unit and if required replace the module.
Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE (OFF1, OFF2, OFF3)
VECTOR: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
F30047 Cooling system: Cooling medium flow rate too low
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Cooling system: Fault - flow rate has fallen below the fault value
Remedy:
F30050 Power unit: Supply overvoltage
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: The following applies for CU31x and CUA31:
- the voltage monitoring on the DAC board signals an overvoltage fault on the module.
Remedy: - check the voltage supply for the Control Unit (24 V).
- if required, replace the module.
