Faults and alarms
List of faults and alarms
This message can be acknowledged without a POWER ON as follows:
- via F-DI or PROFIsafe.
Note:
F-DI: Failsafe Digital Input
SAM: Safe Acceleration Monitor (safe acceleration monitoring)
SBR: Safe Brake Ramp (safe brake ramp monitoring)
C01701 SI Motion P1: STOP B initiated
Reaction: NONE (OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP B (braking along the OFF3 deceleration ramp).
As a result of this fault, after the speed threshold parameterized in p9560 is fallen below, message C01700 "STOP
A initiated" is output.
Possible causes:
- stop request from processor 2.
- Subsequent response to the message C01714 "SI Motion P1: Safely-Limited Speed exceeded".
- subsequent response to the message C01711 "SI Motion P1: Defect in a monitoring channel".
- subsequent response to the message C01707 "SI Motion P1: tolerance for safe operating stop exceeded".
Remedy: - remove the cause of the fault on the monitoring channel of processor 2.
- carry out a diagnostics routine for message C01714.
- carry out a diagnostics routine for message C01711.
- carry out a diagnostics routine for message C01707.
This message can be acknowledged without a POWER ON as follows:
- motion monitoring functions integrated in the drive: F-DI or PROFIsafe.
Note:
F-DI: Failsafe Digital Input
C01706 SI Motion P1: SAM/SBR limit exceeded
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Motion monitoring functions with set acceleration monitoring (SAM, p9506 = 3):
- after initiating STOP B (SS1) the velocity has exceeded the selected tolerance.
Motion monitoring functions with set brake ramp monitoring (SBR, p9506 = 1):
- after initiating STOP B (SS1) or SLS changeover to the lower speed stage, the speed has exceeded the selected
tolerance.
The drive is shut down by the message C01700 "SI Motion: STOP A initiated".
Remedy: Check the braking behavior and, if necessary, adapt the parameterization of the parameter settings of the "SAM" or
the "SBR" function.
This message can be acknowledged without a POWER ON as follows:
- motion monitoring functions integrated in the drive: via F-DI or PROFIsafe.
Note:
F-DI: Failsafe Digital Input
SAM: Safe Acceleration Monitor (safe acceleration monitoring)
SBR: Safe Brake Ramp (safe brake ramp monitoring)
SI: Safety Integrated
See also: p9548 (SI Motion SAM actual velocity tolerance (processor 1)), p9581 (SI Motion brake ramp reference
value (processor 1)), p9582 (SI Motion brake ramp delay time (processor 1)), p9583 (SI Motion brake ramp monitor-
ing time (processor 1))
C01711 SI Motion P1: Defect in a monitoring channel
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
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 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.
