C01711 SI Motion P1 (CU): Defect in a monitoring channel
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: When cross-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 message C01701 "SI Motion: STOP B initiated" is output.
The message value that resulted in a STOP F is displayed in r9725. The message values described involve the
crosswise data comparison between processor 1 and processor 2.
The following message values may also occur in the following cases if the cause that is explicitly mentioned does not
apply:
- synchronization error between processor 1 and processor 2.
Message value (r2124, interpret decimal):
0 to 999: Number of the cross-compared data that resulted in this fault.
0: Stop request from the other monitoring channel.
1: Status image of monitoring functions SLS or SAM/SBR (result list 1) (r9710[0], r9710[1]).
2: Status image of monitoring function n < nx (result list 2) (r9711[0], r9711[1]).
3: The position actual value differential (r9713[0/1]) between the two monitoring channels is greater than the
tolerance in p9542/p9342.
4: Error when synchronizing the crosswise data comparison between the two channels.
5: Function enable signals (p9501/p9301) Safety monitoring clock cycle too small (p9500/p9300).
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])
31: Position tolerance (p9542/p9342).
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 actual value (r9713[0/1]). 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
message value 3). This can be ascertained by checking the safe actual positions.
Permissible deviation between the two monitoring channels: p9542/p9342.
44: Position actual value (r9713[0/1]) + limit value SLS1 (p9531[0]/p9331[0]) * safety monitoring clock cycle (12 ms).
45: Position actual value (r9713[0/1]) - limit value SLS1 (p9531[0]/p9331[0]) * safety monitoring clock cycle (12 ms).
46: Position actual value (r9713[0/1]) + limit value SLS2 (p9531[1]/p9331[1]) * safety monitoring clock cycle (12 ms).
47: Position actual value (r9713[0/1]) - limit value SLS2 (p9531[1]/p9331[1]) * safety monitoring clock cycle (12 ms).
48: Position actual value (r9713[0/1]) + limit value SLS3 (p9531[2]/p9331[2]) * safety monitoring clock cycle (12 ms).
49: Position actual value (r9713[0/1]) - limit value SLS3 (p9531[2]/p9331[2]) * safety monitoring clock cycle (12 ms).
50: Position actual value (r9713[0/1]) + limit value SLS4 (p9531[3]/p9331[3]) * safety monitoring clock cycle (12 ms).
51: Position actual value (r9713[0/1]) - limit value SLS4 (p9531[3]/p9331[3]) * safety monitoring clock cycle (12 ms).
54: Position actual value (r9713[0/1]) + limit value nx (p9546/p9346) * safety monitoring clock cycle (12 ms) +
tolerance (p9542/p9342).
55: Position actual value (r9713[0/1]) + limit value nx (p9546/p9346) * safety monitoring clock cycle (12 ms).
56: Position actual value (r9713[0/1]) - limit value nx (p9546/p9346) * safety monitoring clock cycle (12 ms).
57: Position actual value (r9713[0/1]) - limit value nx (p9546/p9346) * safety monitoring clock cycle (12 ms) -
tolerance (p9542/p9342).
58: Actual stop request.
75: Velocity limit nx (p9546, p9346).
76: Stop response for SLS1 (p9563[0]/p9363[0])
77: Stop response for SLS2 (p9563[1]/p9363[1])
