Cause : Monitoring time sign-of-life expired comes when the monitoring time for the sign-of-life counter has expired.
The connection between the drive and the higher-level control (SIMOTION, SINUMERIK) has been interrupted for the following reasons:
- the control was reset.
- the data transfer to the control was interrupted.
- wait until the control has re-booted.
- restore data transfer to the control.
