The frequency converter is switched off immediately. The motor is stopped by the
external brake. If there isn't an external brake, the motor will stop of its own
accord.
The AUS2 command has a higher priority than AUS1 and AUS3. In other words, a
normal ramp down or an abrupt stop is canceled by AUS2.
If AUS2 is used together with a brake, overload or overvoltage diagnoses may be
obtained.
