Overview of Alarms
Cause: The drive is stopped via a STOP A (pulses are cancelled via the safety shutdown path of
the control unit).
Possible causes:
- stop request from the higher-level control.
- pulses not cancelled after a parameterized time (p9557) after test stop selection.
- subsequent response to the message C01706 "SI Motion: Safe braking ramp exceeded".
- subsequent response to the message C01714 "SI Motion: Safe speed exceeded".
- subsequent response to the message C01701 "SI Motion: STOP B initiated".
Remedy: - remove the fault cause in the control and carry-out a POWER ON.
- check the value in p9557, if necessary, increase the value, and carry-out POWER ON.
- check the shutdown path of control unit (check DRIVE-CLiQ communications).
- carry-out a diagnostics routine for message C01706.
- carry-out a diagnostics routine for message C01714.
- carry-out a diagnostics routine for message C01701.
- replace motor module.
- replace control unit.
Note:
SI: Safety Integrated
201701 <location>SI motion: STOP B initiated
Reaction: OFF3
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP B (braked along the current limit).
As a result of this fault, after the time, parameterized in p9556 has expired, or the speed
threshold, parameterized in p9560 has been fallen below, message C01700 "STOP A
initiated" is output.
Possible causes:
- stop request from the higher-level control.
- subsequent response to the message C01714 "SI Motion: Safely reduced speed
exceeded".
- subsequent response to the message C01711 "SI Motion: Defect in a monitoring
channel".
Remedy: - remove the fault cause in the control and carry-out a POWER ON.
- carry-out a diagnostics routine for message C01714.
- carry-out a diagnostics routine for message C01711.
Note:
SI: Safety Integrated
201706 <location>SI motion: Safe braking ramp exceeded
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: After initiating STOP B or STOP C, the velocity has exceeded the selected tolerance.
The drive is shut down by the message C01700 "SI Motion: STOP A initiated".
Remedy: Check the braking behavior, if required, adapt the tolerance for "safe braking ramp" (SBR).
Note:
SBR: Safe braking ramp
SI: Safety Integrated
See also: p9548
201707 <location>SI motion: Tolerance for safe operating stop exceeded
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The actual position has distanced itself further from the target position than the standstill
tolerance.
The drive is stopped by the message C01701 "SI Motion: STOP B initiated".
