Siemens SIMOTICS S-1FK2, Operating Instructions Manual

Page: 382 / 768

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 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 following described message values involve the data cross-check between the two monitoring channels (safety
functions integrated in the drive).
The message values may also occur in the following cases if the cause that is explicitly mentioned does not apply:
- For message values 3, 44 ... 57, 232 and 1-encoder system, differently set encoder parameters.
- incorrect synchronization.
Message value (r2124, interpret decimal):
0 to 999: number of the cross-compared 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, SAM/SBR or SDI (result list 1) (r9710[0], r9710[1]).
2: Status image of monitoring function SSM (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.
4: Error when synchronizing the data cross-check 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]).
7: Limit value for SLS2 (p9531[1]).
8: Limit value for SLS3 (p9531[2]).
9: Limit value for SLS4 (p9531[3]).
10: Standstill tolerance (p9530).
31: Position tolerance (p9542/p9342) or (p9549/p9349) when actual value synchronization is enabled (p9501.3)
33: Time, speed switchover (p9551)
35: Delay time, STOP A (p9556).
36: Test time, STO (p9557).
37: Transition time, STOP C to SOS (p9552).
38: Transition time STOP D to SOS (p9553)
40: Stop response for SLS (p9561).
42: Shutdown speed STO (p9560).
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.
44: Position actual value (r9713[0/1]) + limit value SLS1 (p9531[0]) * safety monitoring clock cycle.
45: Position actual value (r9713[0/1]) + limit value SLS1 (p9531[0]) * safety monitoring clock cycle.
46: Position actual value (r9713[0/1]) + limit value SLS2 (p9531[1]) * safety monitoring clock cycle.
47: Position actual value (r9713[0/1]) + limit value SLS2 (p9531[1]) * safety monitoring clock cycle.
48: Position actual value (r9713[0/1]) + limit value SLS3 (p9531[2]) * safety monitoring clock cycle.
49: Position actual value (r9713[0/1]) - limit value SLS3 (p9531[2]) * safety monitoring clock cycle.
50: Position actual value (r9713[0/1]) + limit value SLS4 (p9531[3]) * safety monitoring clock cycle.
51: Position actual value (r9713[0/1]) - limit value SLS4 (p9531[3]) * safety monitoring clock cycle.
52: Standstill po tolerance (p9530).
53: Standstill position - tolerance (p9530).
