SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Remedy: - carry out a POWER ON.
- replace the Control Unit.
A01251 CU: CU-EEPROM incorrect read-write data
Reaction: NONE
Acknowledge: NONE
Cause: Error when reading the read-write data of the EEPROM in the Control Unit.
Alarm value (r2124, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: For alarm value r2124 < 256, the following applies:
- carry out a POWER ON.
- replace the Control Unit.
For alarm value r2124 >= 256, the following applies:
- clear the fault memory (p0952 = 0).
- replace the Control Unit.
F01257 CU: Firmware version out of date
Reaction: OFF2
Acknowledge: POWER ON
Cause: The Control Unit firmware is too old.
Fault value (r0949, interpret hexadecimal):
bbbbbbaa hex: aa = unsupported component
aa = 01 hex = 1 dec:
The firmware being used does not support the Control Unit.
aa = 02 hex = 2 dec:
The firmware being used does not support the Control Unit.
aa = 03 hex = 3 dec:
The firmware being used does not support the Power Module.
aa = 04 hex = 4 dec:
The firmware being used does not support the Control Unit.
Remedy: Re fault value = 1, 2, 4:
- Upgrade the firmware of the Control Unit.
For fault value = 3:
- Upgrade the firmware of the Control Unit.
- Replace the Power Module by a component that is supported.
F01340 Topology: Too many components on one line
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: For the selected communications clock cycle, too many DRIVE-CLiQ components are connected to one line of the
Control Unit.
Fault value (r0949, interpret hexadecimal):
xyy hex: x = fault cause, yy = component number or connection number.
1yy:
The communications clock cycle of the DRIVE-CLiQ connection on the Control Unit is not sufficient for all read trans-
fers.
2yy:
The communications clock cycle of the DRIVE-CLiQ connection on the Control Unit is not sufficient for all write trans-
fers.
3yy:
Cyclic communication is fully utilized.
4yy:
The DRIVE-CLiQ cycle starts before the earliest end of the application. An additional dead time must be added to
the control. Sign-of-life errors can be expected.
The conditions of operation with a current controller sampling time of 31.25 µs have not been maintained.
5yy:
Internal buffer overflow for net data of a DRIVE-CLiQ connection.
6yy:
Internal buffer overflow for receive data of a DRIVE-CLiQ connection.
7yy:
Internal buffer overflow for send data of a DRIVE-CLiQ connection.
