cause : STOP E initiated comes when the drive is stopped via a STOP E (retraction motion). "Safe Operating Stop" (SOS) is activated after the parameterized time has expired.

Possible causes:
- stop request from the higher-level control.
- subsequent response to the message C01714 "SI Motion CU: Safely-Limited Speed exceeded".
- subsequent response to the message C01715 "SI Motion CU: Safely-limited position exceeded".
- subsequent response to the message C01716 "SI Motion CU: tolerance for safe motion direction exceeded".

See also: p9554 (SI Motion transition time STOP E to SOS (SBH) (Control Unit)).

- remove the cause of the fault at the control.
- carry out a diagnostics routine for message C01714/C01715/C01716.

This message can be acknowledged as follows:
- motion monitoring functions integrated in the drive: Via Terminal Module 54F (TM54F) or PROFIsafe
- motion monitoring functions with SINUMERIK: Via the machine control panel.
