Voltage Controller - BONFIGLIOLI ACTIVE Cube ACU 201-01 Operating Instructions Manual

If the output current has already been reduced due to the fact that the long-term
overload has used up, the short-term overload is no longer available even if it has not
been used up beforehand. The defined overload reserve (Ixt) of the frequency in-
verter is available again after a power reduction lasting 10 minutes.
Output signals
Digital outputs can signalize the achievement of a limit value – selected in
573.

Voltage controller

The voltage controller contains the functions necessary for monitoring the DC link
voltage.
The DC link voltage which rises in generator operation or in the braking process
−
of the 3-phase machine is controlled to the set limit value by the voltage control-
ler.
The power failure regulation uses the rotation energy of the drive to bridge short-
−
term power failures.
The voltage controller is set with the parameter
with the application.

The function is switched off. Brake and Motor chopper
are active and switch with the parameterized thresh-
olds of P506 and P507.
DC link limitation active. Overvoltage controller
switched on, the Brake and Motor chopper are active
and switch with the parameterized thresholds of P506
and P507. Factory setting.
Power failure regulation switched on. Brake and Motor
chopper are active and switch with the parameterized
thresholds of P506 and P507. Suitable for quick shut-
down.
Overvoltage controller and power failure regulation
switched on, with motor chopper.
Power failure regulation switched on. During the
Mains Support, motor and brake chopper are deac-
tivated. In all other cases motor and brake chopper
are active and switch with the parameterized thresh-
olds of P506 and P507.
Overvoltage controller and power failure regulation
switched on. During the Mains Support, motor and
brake chopper are deactivated. In all other cases
motor and brake chopper are active and switch with
the parameterized thresholds of P506 and P507.
