SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
F30850 Power unit: Internal software error
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: POWER ON
Cause: An internal software error has occurred in the power unit.
Fault value (r0949, decimal interpretation):
Only for internal Siemens troubleshooting.
Remedy: - replace power unit.
- if required, upgrade the firmware in the power unit.
- contact the Hotline.
F30903 Power unit: I2C bus error occurred
Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: Communications error with an EEPROM or A/D converter.
Fault value (r0949, interpret hexadecimal):
80000000 hex:
- internal software error.
00000001 hex ... 0000FFFF hex:
- module fault.
Remedy: Re fault value = 80000000 hex:
- upgrade firmware to later version.
Re fault value = 00000001 hex ... 0000FFFF hex:
- replace the module.
A30920 (F) Temperature sensor fault
Reaction: NONE
Acknowledge: NONE
Cause: When evaluating the temperature sensor, an error occurred.
Alarm value (r2124, interpret decimal):
1: Wire breakage or sensor not connected (KTY: R > 2120 Ohm).
2: Measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm).
Remedy: - make sure that the sensor is connected correctly.
- replace the sensor.
A30999 (F, N) Power unit: Unknown alarm
Reaction: NONE
Acknowledge: NONE
Cause: An alarm occurred on the power unit that cannot be interpreted by the Control Unit firmware.
This can occur if the firmware on this component is more recent than the firmware on the Control Unit.
Alarm value (r2124, interpret decimal):
Alarm number.
Note:
If required, the significance of this new alarm can be read about in a more recent description of the Control Unit.
Remedy: - replace the firmware on the power unit by an older firmware version (r0128).
- upgrade the firmware on the Control Unit (r0018).
F50510 FBLOCKS: Logon of the run-time group rejected
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: When the run-time groups of the free function blocks attempted to log on with the sampling time management, the
logon of at least one run-time group was rejected.
Too many different hardware sampling times may have been assigned to the free function blocks.
Remedy: - Check number of available hardware sampling times (T_sample < 8 ms) (r7903).
