201224 <location>CU: Pulse frequency inconsistent
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: When changing the minimum pulse frequency (p0113) inconsistency between the pulse frequencies
was identified.
Alarm value (r2124, interpret decimal):
1: Value, low minimum value.
2: Value, high maximum value.
3: Resulting sampling time is not a multiple of 1.25 µs.
4: Value does not match clock-cycle synchronous PROFIBUS operation.
10: Special restriction of the drive object violated.
99: Inconsistency of cross drive objects detected.
116: Recommended clock cycle in r0116[0...1].
Remedy: Set a valid pulse frequency.

201250 <location>CU: CU-EEPROM incorrect read-only data
Message %1
value:
Drive object: All objects
Reaction: NONE (OFF2)
Acknowledge: POWER ON
Cause: Error when reading the read-only data of the EEPROM in the Control Unit.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON.
- replace the Control Unit.
201251 <location>CU: CU-EEPROM incorrect read-write data
Message %1
value:
Drive object: All objects
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:
- for the drive object with this alarm, clear the fault memory (p0952 = 0).
- as an alternative, clear the fault memory of all drive objects (p2147 = 1).
- replace the Control Unit.
201255 <location>CU: Option Board EEPROM read-only data error
Message %1
value:
Drive object: All objects
Reaction: NONE (OFF2)
Acknowledge: POWER ON
Cause: Error when reading the read-only data of the EEPROM in the Option Board.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON.
- replace the Control Unit.
