Disabling and re-enabling operation
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.
In contrast to the AUS2 command (see above), the frequency converter does not
enter the starting lockout state. It is therefore not necessary to switch on control
bit 0 again.
“Disable operation” does not have a higher priority than AUS1 and AUS3. In other
words, it will not affect a ramp down or rapid stop that has already started.
