10.4 Behaviour in the event of mains switching, mains failure or controller inhibit
10.4.1 Start conditions/flying−restart circuit
Description
Determines the controller behaviour after a restart after controller inhibit, mains
switching or a mains failure.
With activated flying−restart circuit the controller automatically synchronises to a
coasting motor after mains disconnection or adds a setpoint signal.

Drive behaviour without flying−restart circuit
Manual start (C0142 = 0):
After mains interruption the drive only restarts after a LOW/HIGH level change at the
"Controller inhibit" terminal (X3/28).
Automatic start (C0142 = 1)
After mains interruption the drive only restarts if a HIGH level is applied to the "controller
inhibit"terminal (X3/28).
The controller sets all integrators to zero and releases them again.
Drive behaviour with flying−restart circuit
Manual start with flying−restart circuit (C0142 = 2)
After mains interruption the drive only restarts after a LOW/HIGH level change at the
"Controller inhibit" terminal (X3/28).
Automatic start with flying−restart circuit (C0142 = 3)
After mains interruption the drive only restarts if a HIGH level is applied to the "controller
inhibit"terminal (X3/28).
