4 Faults and alarms
4.2 List of faults and alarms
A01698 (F) SI P1 (CU): Commissioning mode active
Message class: General drive fault (19)
Reaction: NONE
Acknowledge: NONE
Cause: The commissioning of the "Safety Integrated" function is selected.
This message is withdrawn after the safety functions have been commissioned.
Note:
- this message does not result in a safety stop response.
- in the safety commissioning mode, the "STO" function is internally selected.
See also: p0010 (Drive commissioning parameter filter)
Remedy: Not necessary.
A01699 (F) SI P1 (CU): Test stop for STO required
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: NONE
Cause: The time set in p9659 for the forced checking procedure (test stop) for the "STO" function has been exceeded. A new
forced checking procedure is required.
After the next time the "STO" function is de-selected, the message is withdrawn and the monitoring time is reset.
Note:
- this message does not result in a safety stop response.
- The test must be performed within a defined, maximum time interval (p9659, maximum of 9000 hours) in order to
comply with the requirements as laid down in the standards for timely fault detection and the conditions to calculate
the failure rates of safety functions (PFH value). Operation beyond this maximum time period is permissible if it can
be ensured that the forced checking procedure is performed before persons enter the hazardous area and who are
depending on the safety functions correctly functioning.
See also: p9659 (SI forced checking procedure timer), r9660 (SI forced checking procedure remaining time)
Remedy: Select STO and then de-select again.
Note:
SI: Safety Integrated
STO: Safe Torque Off
C01700 SI Motion P1 (CU): STOP A initiated
Message class: Safety monitoring channel has identified an error (10)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP A (pulses are suppressed via the safety switch-off signal path of processor 1).
Possible causes:
- stop request from processor 2.
- pulses not suppressed after test stop selection.
- subsequent response to the message C01706 "SI Motion P1: SAM/SBR limit exceeded".
- Subsequent response to the message C01714 "SI Motion P1: Safely Limited Speed exceeded".
- Subsequent response to the message C01701 "SI Motion P1: STOP B initiated".
Remedy: - remove the cause of the fault on the monitoring channel of processor 2.
- carry out a diagnostics routine for message C01706.
- carry out a diagnostics routine for message C01714.
- carry out a diagnostics routine for message C01701.
- check the switch-off signal path of processor 1.
- replace Power Module.
- replace Control Unit.
This message can be acknowledged without a POWER ON using "Acknowledge internal event":
Note:
SAM: Safe Acceleration Monitor (safe acceleration monitoring)
SBR: Safe Brake Ramp (safe brake ramp monitoring)
