4 Faults and alarms
4.2 List of faults and alarms
28: Encoderless monitoring functions are not supported for synchronous motors (p9507.2).
55: Encoderless monitoring functions are not supported for reluctance motors.
Remedy: De-select the monitoring function involved (p9501, p9601, p9801).
Note:
SCA: Safe Cam
SDI: Safe Direction (safe motion direction)
SLP: Safely Limited Position
SLS: Safely Limited Speed
See also: p9501 (SI Motion enable safety functions (processor 1)), r9771 (SI common functions (processor 1))
F01683 SI Motion P1 (CU): SLS enable missing
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The safety-relevant function "SLS" is not enabled in p9501 although other safety-relevant monitoring functions are
enabled.
Note:
This fault does not result in a safety stop response.
Remedy: Enable the function "SLS" (p9501.0) and carry out a POWER ON.
Note:
Save the changes before POWER ON (copy from RAM to ROM).
SLS: Safely Limited Speed

F01690 SI Motion: Data save problem for the NVRAM
Message class: Hardware/software error (1)
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: POWER ON
Cause: There is not sufficient memory space in the NVRAM on the drive to save parameters r9781 and r9782 (safety
logbook).
Note:
This fault does not result in a safety stop response.
Fault value (r0949, interpret decimal):
0: There is no physical NVRAM available in the drive.
1: There is no longer any free memory space in the NVRAM.
Remedy: For fault value = 0:
- use a Control Unit NVRAM.
For fault value = 1:
- de-select functions that are not required and that take up memory space in the NVRAM.
- contact Technical Support.
Note:
NVRAM: Non-Volatile Random Access Memory (non-volatile read and write memory)
F01692 SI Motion P1 (CU): Parameter value not permitted for encoderless
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: For encoderless motion monitoring functions, the parameter cannot be parameterized with this value.
Note:
This fault does not result in a safety stop response.
Fault value (r0949, interpret decimal):
Parameter number with the incorrect value.
See also: p9501 (SI Motion enable safety functions (processor 1))
Remedy: Correct the parameter specified in the fault value.
