SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
SI motion: STOP A initiated
OFF2
IMMEDIATELY (POWER ON)
The drive is stopped using a STOP A (the pulses are cancelled via the
safety shutdown path of the Control Unit).
Possible causes:
– Stop request from the higher–level control.
– Pulses have not been cancelled after a parameterized time (p9557)
after the test stop was selected.
– Subsequent response of message C01706 "SI motion: Safe
acceleration monitoring exceeded".
– Subsequent response of message C01714 "SI motion: Safely
reduced speed exceeded".
– Subsequent response of message C01701 "SI motion: STOP B
initiated".
Remove the cause of the fault on the control and carry out a power on.
– Check the value in p9557 – if required increase the value and carry
out a power on.
– Check the shutdown path of the Control Unit (check DRIVE–CLiQ
communications).
– Carry out diagnostics for message C01706.
– Carry out diagnostics for message C01714.
– Carry out diagnostics for message C01701.
– Replace the module.
– Replace the Control Unit
SI motion: STOP B activated
OFF3
IMMEDIATELY (POWER ON)
The drive is stopped using STOP B (braking along the OFF3 ramp).
As a result of this fault, after the time parameterized in p9556 has ex-
pired 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 of message C01714 "SI motion: Safely
reduced speed exceeded".
– Subsequent response of message C01711 "SI motion: Defect in a
monitoring channel".
Remove the cause of the fault on the control and carry out a power on.
– Carry out diagnostics for message C01714.
– Carry out diagnostics for message C01711.
