A30044 (F) Power unit: Overvoltage 24 V alarm
Message value: %1
Message class: Supply voltage fault (undervoltage) (3)
Drive object: B_INF
Reaction: NONE
Acknowledge: NONE
Cause: For the power unit power supply, the upper threshold has been violated.
Alarm value (r2124, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: Check the power supply of the power unit.
Reaction upon F: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
F30045 Power unit: Supply undervoltage
Message value: %1
Message class: Supply voltage fault (undervoltage) (3)
Drive object: B_INF, VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Power supply fault in the power unit.
- The voltage monitor signals an undervoltage fault on the module.
The following applies for CU31x:
- the voltage monitoring on the DAC board signals an undervoltage fault on the module.
Remedy: - Check the power supply of the power unit.
- carry out a POWER ON (power off/on) for the component.
- replace the module if necessary.
A30046 (F) Power unit: Undervoltage alarm
Message value: %1
Message class: Power electronics faulted (5)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: Before the last restart, a problem occurred at the power unit power supply.
The voltage monitor in the internal FPGA of the PSA signals an undervoltage fault on the module.
Fault value (r0949, interpret decimal):
Register value of the voltage fault register.
Remedy: - check the 24 V DC voltage supply to power unit.
- carry out a POWER ON (power off/on) for the component.
- replace the module if necessary.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A30046 (F) Power unit: Undervoltage alarm
