Faults and Alarms
List of Faults and Alarms
C30712 SI Motion P2: Defect in F-IO processing
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-checked 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
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.
Remedy: - check the traversing/motion program in the control.
- check the limits for "SLS" function and if required, adapt (p9331).
Note:
This message can be acknowledged via F-DI or PROFIsafe.
SLS: Safely-Limited Speed
See also: p9331 (SI Motion SLS limit values (processor 2)), p9363 (SI Motion SLS stop response (processor 2))
C30716 SI Motion P2: Tolerance for safe motion direction exceeded
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The tolerance for the "safe motion direction" function was exceeded. The drive is stopped as a result of the
configured stop response (p9366).
Message value (r9749, interpret decimal):
0: Tolerance for the "safe motion direction positive" function exceeded.
1: Tolerance for the "safe motion direction positive negative" function exceeded.
Remedy: - check the traversing/motion program in the control.
- check the tolerance for "SDI" function and if required, adapt (p9364).
This message can be acknowledged as follows:
Via F-DI or PROFIsafe
Note:
SDI: Safe Direction (safe motion direction)
SI: Safety Integrated
See also: p9364 (SI Motion SDI tolerance (processor 2)), p9365 (SI Motion SDI delay time (processor 2)), p9366 (SI
Motion SDI stop response (processor 2))
