–
If the logic power supply to the device is still on, the fast discharge of the intermediate circuit is
initiated.
–
The pre-charge relay is opened and this disconnects the intermediate circuit capacitor from the
rectifier.
Controller enable
Various options are available for requesting controller enable. Parameters can be defined for how the
request for controller enable is to be triggered. The selection influences the operating mode that will
be activated after the controller enable.
–
If the request is to be sent via the device-specific plug-in or the device profile, the associated
interface must have the master control

Behaviour with controller enable
The motor is energised after controller enable. The closed-loop controller takes control.
