Overview of Alarms
Remedy: - remove the fault cause in the control and carry-out a POWER ON.
- carry-out a diagnostics routine for message C01714.
Note:
SBH: Safe operating stop
SI: Safety Integrated
201711 <location>SI motion: 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 function 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 stage 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.
Message value (r9749, decimal):
Value, that resulted in a STOP F.
See also: p9555, r9725
Remedy: The message value contained in r9725 is described in message 27001 of the higher-level
control.
Note:
SI: Safety Integrated
201714 <location>SI motion: Safely reduced speed exceeded
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive had moved faster than that specified by the velocity limit value (p9531). The drive
is stopped as a result of the configured stop response (p9563).
Message value (r9749, decimal):
100: SG1 exceeded.
200: SG2 exceeded..
300: SG3 exceeded.
400: SG4 exceeded.
1000: Encoder limit frequency exceeded.
Remedy: - check the traversing/motion program in the control.
- check the limits for "safely reduced speed (SG) and if required, adapt (p9531).
Note:
SG: Safely-reduced speed
SI: Safety Integrated
See also: p9531, p9563
201798 <location>SI motion: Test stop running
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The test stop is active.
Remedy: None necessary.
The message is withdrawn when the test stop is ended.
Note:
SI: Safety Integrated
201799 <location>SI motion: Acceptance test mode active
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
