Example 2: Internal event with SSM active
Internal event when the motion monitoring function is active
If an active safety function with motion monitoring (SS1, SSL, SDI or SSM) is interrupted with
an internal event, the inverter responds with a STOP F.
A STOP F does not unconditionally stop the motor.
The drive response
The motor behavior is explained using the SSM function and a STOP B with acceleration
monitoring as an example:
