SINAMICS S110 List Manual (LH7), 06/2012, 6SL3097-4AP10-0BP3
A30046 (F) Power unit: Undervoltage, alarm
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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):
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)
A30048 Power unit: External fan faulty
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The feedback signal from the external fan indicates a fault.
- fan faulty, blocked.
- feedback signal inaccurate.
Remedy: - check the external fan and replace if necessary.
- if you are using an external fan with feedback, check its wiring (X12.2 or X13.2).
Note:
If you are using an external fan without feedback, check that the feedback terminal wiring on the power unit is con-
nected to ground and make this connection if necessary (X12.1/2 or X13.1/2).
A30049 Power unit: Internal fan faulty
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The internal fan has failed.
Remedy: Check the internal fan and replace if necessary.
F30050 Power unit: 24 V supply overvoltage
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2
Acknowledge: POWER ON
Cause: The voltage monitor signals an overvoltage fault on the module.
Remedy: - check the 24 V power supply.
- replace the module if necessary.
F30052 EEPROM data error
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: POWER ON
Cause: EEPROM data error of the power unit module.
