Si Motion Cu: Defect In A Monitoring Channel - Siemens Sinamics S120 Diagnostic Manual

201711 <location>SI Motion CU: Defect in a monitoring channel
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: When cross-checking and comparing the two monitoring channels, the drive detected a difference between the input
data or results of the monitoring functions and initiated a STOP F. One of the monitoring functions no longer reliably
functions - i.e. safe operation is no longer possible.
If at least one monitoring function is active, then after the parameterized timer has expired, the message C01701 "SI
Motion: STOP B initiated" is output.
The message value that resulted in a STOP F is displayed in r9725. The described message values involve the data
cross-check between the Control Unit and Motor Module. If the drive is operated together with a SINUMERIK, the mes-
sage values are described in message 27001 of SINUMERIK.
The following message values may also occur in the following cases if the cause that is explicitly mentioned does not
apply:
- cycle times not set uniformly (p9500/p9300 and p9511/p9311)
- differently parameterized axis types (p9502/p9302).
- excessively fast cycle times (p9500/p9300, p9511/p9311).
- for message values 3, 44 ... 57, 232, and encoder systems, differently parameterized encoder values (p9516/p9316,
p9517/p9317, p9518/p9318, p9520/p9320, p9521/p9321, p9522/p9322, p9526/p9326).
- incorrect synchronization.
Message value (r9749, interpret decimal):
0 to 999: Number of the cross-checked data that resulted in this fault.
Message values that are not subsequently listed are only for internal Siemens troubleshooting.
0: Stop request from the other monitoring channel.
1: Status image of monitoring functions SOS, SLS or SLP (result list 1) (r9710[0], r9710[1]).
2: Status image of monitoring function SCA or n < nx (result list 2) (r9711[0], r9711[1]).
3: The position actual value differential (r9713) between the two monitoring channels is greater than the tolerance in
p9542/p9342. When actual value synchronization is enabled (p9501.3/p9301.3), the velocity differential (based on the
position actual value) is greater than the tolerance in p9549/p9349.
4: Error when synchronizing the crosswise data comparison between the two channels.
5: Function enable signals (p9501/p9301)
6: Limit value for SLS1 (p9531[0]/p9331[0])
7: Limit value for SLS2 (p9531[1]/p9331[1])
8: Limit value for SLS3 (p9531[2]/p9331[2])
9: Limit value for SLS4 (p9531[3]/p9331[3])
10: Standstill tol. (p9530/p9330)
31: Position tolerance (p9542/p9342) or (p9549/p9349) when actual value synchronization is enabled (p9501.3/
p9301.3)
33: Time, velocity changeover (p9551/p9351)
35: Delay time, pulse canc. (p9556/p9356)
36: Checking time, pulse canc. (p9557/p9357)
37: Trans. time, STOP C to SOS (p9552/p9352)
38: Trans. time STOP D to SOS (p9553/p9353)
40: Stop response for SLS (p9561/p9361)
42: Shutdown speed, pulse canc. (p9560/p9360)
43: Memory test, stop response (STOP A).
44 ... 57: General
Possible cause 1 (during commissioning or parameter modification)
The tolerance value for the monitoring function is not the same on the two monitoring
channels.
Possible cause 2 (during active operation)
The limit values are based on the current actual value (r9713). If the safe actual values on the two monitoring channels
do not match, the limit values, which have been set at a defined interval, will also be different (i.e. corresponding to
fault value 3). This can be ascertained by checking the safe actual positions.
