The motor is stopped by means of a steeper ramp based on half the
parameterized ramp-down time.
The AUS3 command has a higher priority than AUS1. In other words, ramp down
triggered by AUS1 is continued by AUS3 as a rapid stop.
Caution
!
Frequent braking operations with high power consumption can heat up the motor
significantly, possibly resulting in excess temperature.
