Si Motion: Ti And To Unsuitable For Dp Cycle; Si Motion Cu: Parameter Value Not Permitted For Encoderless; Safety Parameter Setting Changed, Wam Restart/Power On Required - Siemens Sinamics S120 Diagnostic Manual

201691 <location>SI Motion: Ti and To unsuitable for DP cycle
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: The configured times for PROFIBUS communication are not permitted and the DP cycle is used as the actual value
acquisition cycle for the safe movement monitoring functions:
Isochronous PROFIBUS: the total of Ti and To is too high for the set DP cycle. The DP cycle should be at least 1 cur-
rent controller cycle greater than the sum of Ti and To.
Non-isochronous PROFIBUS: the DP cycle must be at least 4 x current controller cycle.
Remedy: Configure Ti and To low so that they are suitable for the DP cycle or increase the DP cycle time.
Alternative when drive-based SI monitoring is enabled (p9601/p9801 > 0):
Use the actual value acquisition cycle p9511/p9311 and, in turn, set independently from DP cycle. The actual value
sensing clock cycle must be at least four times the current controller clock cycle. A clock cycle ratio of at least 8:1 is
recommended.

201692 <location>SI Motion CU: Parameter value not permitted for encoderless
Message value: Parameter: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
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 (SI Motion enable safety functions (Control Unit))
Remedy: - Correct the parameter specified in the fault value.
- If necessary, de-select encoderless motion monitoring functions (p9506).

201693 <location>SI Motion CU: Safety parameter setting changed, wam restart/POWER ON
required
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828, TM54F_MA, TM54F_SL
Reaction: NONE
Acknowledge: NONE
Cause: Safety parameters have been changed; these will only take effect following a warm restart or POWER ON.
Alarm value (r2124, interpret decimal):
Parameter number of the safety parameter which has changed, necessitating a warm restart or POWER ON.
Remedy: - carry out a warm restart (p0971 = 3)
- carry out a POWER ON (power off/on) for all components.
