5. Proportional gain and adaptation of the DC−bus voltage controller:
– C0974 = 1006 (FIXED100% to MFAIL−CONST)
– C0973 = 1000 (FIXED0% to MFAIL−ADAPT)
6. Establish the restart protection
– C0976 = 6100 (MFAIL−NOUT to MCTRL−NACT)
– C0975 = 19538 (C0472/18 to MFAIL−THRESHOLD)
– Under C0472/18, first, enter approx. 2 % (reference: n
max
C0011)
7. Connect the reset input (here, with terminal X5/E5 TRIP−RESET):
– C0972 = 55 (DIGIN5 to MFAIL−RESET)
8. Enter all functions blocks which are used (except for codes and digital inputs DIGIN) at free
positions into the processing table under C0465.
Tip!
Use C0003 to save all settings in a parameter set , if they are to be retained on power−off.
Activation
l MFAIL−FAULT = HIGH activates the mains failure control.
l MFAIL−FAULT = LOW triggers a timing element. After elapse of the preset time under C0983,
the mains failure control is ended/cancelled. (

– The drive is accelerated to the speed setpoint, if the restart protection is not active.
– The drive is still braked to zero speed, if the restart protection is active. ( ¶ 2−125, restart
protection)
– When restart protection is active, the drive can only be reset with MFAIL−RESET = HIGH.
