Fpga Data Faulty; Power Unit: Undervoltage When Opening The Brake; Pre-Charge Contactor Monitoring - Siemens Sinamics S120 Diagnostic Manual

Cause: EEPROM data error of the power unit module.
Fault value (r0949, interpret hexadecimal):
0: The EEPROM data read in from the power unit module is inconsistent.
1: EEPROM data is not compatible to the firmware of the power unit application.
Additional values:
Only for internal Siemens troubleshooting.
Remedy: Re fault value = 0:
Replace the power unit module or update the EEPROM data.
Re fault value = 1:
The following applies for CU31x and CUA31:
Update the firmware \SIEMENS\SINAMICS\CODE\SAC\cu31xi.ufw (cua31.ufw)
230053 <location>FPGA data faulty
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: POWER ON
Cause: Power unit module FPGA data error.
Remedy: Replace the power unit module or update the FPGA data.
230054 <location>Power unit: Undervoltage when opening the brake
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: When the brake is being opened, it is detected that the 24 V supply voltage is less than 24 V - 10 % = 21.6 V.
Alarm value (r2124, interpret decimal):
Supply voltage fault [resolution = 0.1 V].
Example:
Alarm value = 212 --> voltage = 21.2 V
Remedy: Check the 24 V supply voltage to the power unit.
230060 <location>Pre-charge contactor monitoring
Message value: Fault cause: %1 bin
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: At the end of the monitoring time (p0255[0]), the actual state of the pre-charge contactor does not match the desired
state.
Bit 0: Monitoring time exceeded.
Bit 1: Contactor opened during operation.
Bit 2: Contactor closed in OFF state.
Remedy: - check the monitoring time setting p0255[0].
- check the contactor wiring and activation.
- replace the contactor.
