Siemens SINAMICS S210 - SI Motion: Ti and to Unsuitable for PN Cycle; SI Motion P1 (CU): Parameter Value Not Permitted for Encoderless

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):
1: There is no longer any free memory space in the NVRAM.
Remedy: 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)
A01691 (F) SI Motion: Ti and To unsuitable for PN cycle
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The configured times for PROFINET communication are not permitted and the PN cycle is used as the actual value
acquisition cycle for the safe movement monitoring functions:
Isochronous PROFINET:
The sum of Ti and To is too high for the selected PN cycle. The PN clock cycle should be at least 1 current controller cycle
greater than the sum of Ti and To.
No isochronous PROFINET:
The PN clock cycle must be at least 4x the current controller clock cycle.
Notice:
If this alarm is not observed, then message C01711 or C30711 – with the value 1020 ... 1021 – can sporadically occur.
Remedy: Configure Ti and To low so that they are suitable for the PN cycle or increase the PN cycle time.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
F01692 SI Motion P1 (CU): Parameter value not permitted for encoderless
Message value: Parameter: %1
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The parameter cannot be set to this value if encoderless motion monitoring functions have been selected in p9506.
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
Remedy: - correct the parameter specified in the fault value.
- if necessary, de-select encoderless motion monitoring functions (p9506).

A01693 (F) SI P1 (CU): Safety parameter setting changed, warm restart/POWER ON required
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
