List of Faults and Alarms
C01711 SI Motion P1: Defect in a monitoring channel
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 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-checked 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) 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)
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 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.
44: Position actual value (r9713) + limit value for SLS1 (p9531[0]/p9331[0])
45: Position actual value (r9713) - limit value for SLS1 (p9531[0]/p9331[0])
46: Position actual value (r9713) + limit value for SLS2 (p9531[1]/p9331[1])
47: Position actual value (r9713) - limit value for SLS2 (p9531[1]/p9331[1])
48: Position actual value (r9713) + limit value for SLS3 (p9531[2]/p9331[2])
49: Position actual value (r9713) - limit value for SLS3 (p9531[2]/p9331[2])
50: Position actual value (r9713) + limit value for SLS4 (p9531[3]/p9331[3])
51: Position actual value (r9713) - limit value for SLS4 (p9531[3]/p9331[3])
54: Position actual value (r9713) + limit value nx (p9546/p9346) + tolerance (p9542/p9342)
55: Position actual value (r9713) + limit value nx (p9546/p9346)
56: Position actual value (r9713) - limit value nx (p9546/p9346)
57: Position actual value (r9713) - limit value nx (p9546/p9346) - 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])
78: Stop response for SLS3 (p9563[2]/p9363[2])
79: Stop response for SLS4 (p9563[3]/p9363[3])
81: Velocity tolerance for SAM (p9548/p9348)
83: Acceptance test timer (p9558/p9358)
230: Filter time constant for n < nx.
231: Hysteresis tolerance for n < nx.
232: Smoothed velocity actual value.
233: Smoothed velocity actual value + limit value nx / safety monitoring clock cycle + hysteresis tolerance.
234: Smoothed velocity actual value + limit value nx / safety monitoring clock cycle.
235: Smoothed velocity actual value - limit value nx / safety monitoring clock cycle.
236: Smoothed velocity actual value - limit value nx / safety monitoring clock cycle - hysteresis tolerance.

241: Deceleration time for SBR (p9582/p9382).
244: Encoderless actual value sensing filter time (p9587/p9387).
