Cause : STOP B initiated comes when he 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 p9360 is fallen below, message C30700 "STOP A initiated" is output.

Possible causes:

- stop request from processor 1.
- subsequent response to the message C30714 "SI Motion P2: Safely-Limited Speed exceeded".
- subsequent response to the message C30711 "SI Motion P2: Defect in a monitoring channel".
- subsequent response to the message C30707 "SI Motion P2: tolerance for safe operating stop exceeded".

1. remove the cause of the fault on the monitoring channel of processor 1.
2.  carry out a diagnostics routine for message C30714.
3. carry out a diagnostics routine for message C30711.
4. carry out a diagnostics routine for message C30707.
