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 ... 999:
Number of the cross-compared data that resulted in this message.
The significance of the individual message values is described in safety message C01711.
1000: Watchdog timer has expired. Too many signal changes have occurred at the F-DI.
1001: Initialization error of watchdog timer.
1011: Acceptance test status between the monitoring channels differ.
1020: Cyc. communication failure between the monit. cycles.
1040: Pulses suppressed with active encoderless monitoring functions.
1041: Current absolute value too low (encoderless)
1042: Current/voltage plausibility error
1043: Too many acceleration phases
1044: Actual current values plausibility error.
See also: r9725 (SI Motion diagnostics STOP F)
Remedy: For message value = 1040:
- de-select encoderless monitoring functions, select and de-select STO.
- if monitoring function is active, issue "SLS" pulse enable within 5 s of de-selecting STO.
For other message values:
- the significance of the individual message values is described in safety message C01711.
Note:
This message can be acknowledged using "Acknowledge internal event".
C30712 SI Motion P2: Defect in F-IO processing
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: When cross checking and comparing the two monitoring channels, the drive detected a difference between
parameters or results of the F-IO processing and initiated a STOP F. One of the monitoring functions no longer
reliably functions - i.e. safe operation is no longer possible.
The safety message C30711 with message value 0 is also displayed due to initiation of STOP F.
If at least one monitoring function is active, then safety message C30701 "SI Motion: STOP B initiated" is output.
Message value (r2124, interpret decimal):
Number of the cross-compared data that resulted in this message.
See safety message C01712 for a description of the message values.
Remedy: - check parameterization in the parameters involved and correct if required.
- ensure equality by copying the SI data to processor 2 and then carry out an acceptance test.
Note:
This message can be acknowledged via F-DI or PROFIsafe.
C30714 SI Motion P2: Safely limited speed exceeded
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive had moved faster than that specified by the velocity limit value (p9331). The drive is stopped as a result of
the configured stop response (p9363).
Message value (r2124, interpret decimal):
100: SLS1 exceeded.
200: SLS2 exceeded.
300: SLS3 exceeded.
400: SLS4 exceeded.
