; the user can define the voltage manually at parameter
.
The intermediate DC circuit is charged over an internal resistor which is bypassed
when the correct level (80% of UDC) is reached and voltage is stabilised.
Braking chopper
The built-in braking chopper of the drive can be used to handle the energy generated
by a decelerating motor.
When the braking chopper is enabled and a resistor connected, the chopper will start
conducting when the DC link voltage of the drive reaches 780 V. The maximum
braking power is achieved at 840 V.
