Voltage control and trip limits
The control and trip limits of the intermediate DC voltage regulator are relative to an
automatically determined supply voltage. The actual voltage used is shown by
parameter
USED SUPPLY VOLT. The nominal DC voltage (
U
DC
) equals this
value 1.35 times.
Automatic identification of the supply voltage is performed every time the drive is
powered.
The intermediate DC circuit is charged over an internal resistor which is bypassed
when the correct level (80% of
U
DC
) is reached and voltage is stabilised.
Brake chopper
The built-in brake chopper of the drive can be used to handle the energy generated
by a decelerating motor.
For the parameters related to the brake chopper and brake resistor, see parameter
group
. For more information on the brake resistor connection,
see
