C01700 SI Motion P1: STOP A initiated
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP A (pulses are suppressed via the safety shutdown 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 shutdown path of processor 1.
- replace Power Module.
- replace Control Unit.
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: 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 (p9506 = 3):
SAM - safe acceleration monitoring. After initiating STOP B (SS1) the velocity has exceeded the selected tolerance.
Motion monitoring functions with set brake ramp monitoring (p9506 = 1):
SBR - Safe brake ramp monitoring. 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 tolerance for 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)
