4 Faults and alarms
4.2 List of faults and alarms
Bit 6 = 1:
It has been identified that the sensor channel 2 has been replaced.
Remedy: - acknowledge component replacement (p9702 = 29).
- save all parameters (p0977 = 1 or p0971 = 1 or "copy RAM to ROM").
- acknowledge fault (e.g. BI: p2103).
Note:
In addition to the fault, diagnostics bits r9776.2 and r9776.3 are set.

F01641 SI P1 (CU): component replacement identified and save required
Message class: General drive fault (19)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The "Safety Integrated" function integrated in the drive has identified that a component has been replaced.
No additional fault response is initiated, therefore operation of the particular drive is not restricted.
When safety functions are active, after a component has been replaced it is necessary to carry out a partial
acceptance test.
Fault value (r0949, interpret binary):
Bit 0 = 1:
It has been identified that the Control Unit has been replaced.
Bit 1 = 1:
It has been identified that the Motor Module/Hydraulic Module has been replaced.
Bit 2 = 1:
It has been identified that the Power Module has been replaced.
Bit 3 = 1:
It has been identified that the Sensor Module channel 1 has been replaced.
Bit 4 = 1:
It has been identified that the Sensor Module channel 2 has been replaced.
Bit 5 = 1:
It has been identified that the sensor channel 1 has been replaced.
Bit 6 = 1:
It has been identified that the sensor channel 2 has been replaced.
Remedy: - save all parameters (p0977 = 1 or p0971 = 1 or "copy RAM to ROM").
- acknowledge fault (e.g. BI: p2103).

F01649 SI P1 (CU): Internal software error
Message class: Hardware/software error (1)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: An internal error in the Safety Integrated software on processor 1 has occurred.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (switch-off/switch-on).
- re-commission the "Safety Integrated" function and carry out a POWER ON.
- contact Technical Support.
- replace Control Unit.
