BONFIGLIOLI ACTIVE Cube ACU 401-25 User Manual

If the mains failure with or without shutdown takes so long that the frequency in-
verter shuts off completely (LED's = OFF), the frequency inverter will be in the
"Standby" state when the mains supply is restored. If the inverter is released again,
the drive will start. If the drive is to start automatically after restoration of the mai
ns
supply if the inverter is released permanently, Operation mode 651
of Auto Start
must be switched on.

The voltage controller uses the limit values of the DC link voltage. The frequency
change necessary for this is parameterized by the generator reference cur
rent value
or the ramp. The Gen. ref. current limit 683 or the ramp Mains support deceleration
673
defines the maximum deceleration of the drive necessary in order to reach the
voltage value Reference mains support value 672. The Acceleration on mains re-
sumption
674 replaces the set values of the ramp parameters Acceleration (clock-
wise)
420 or Acceleration anticlockwise 422
if the figure set in the factory is
changed. The voltage control in a mains failure changes from the frequency limit
Shutdown threshold 675 from Reference mains support value 672 to the Reference
shutdown
value
676.

The proportional and integrating part of the current controller can be set via parame-
ters Amplification 677 and Integral time 678
. The control functions are deactivated
by setting the parameters to 0. The controllers are P and I controllers in the corre-
sponding settings.
