5.3.1 Braking unit
current.
This leads to an increase in the intermediate circuit voltage.
Braking units (internal to drive or external BUy) are therefore used in order to prevent the DC voltage rising to
resistor (R), thus providing very short deceleration times and restricted four-quadrant operation.
Note! An optional BUy braking unit connected to terminals C and D can be used. For further details reference should be
made to the BUy manual.
Recommended combination braking resistors: see chapter “10.8 Braking resistor (optional)”, page 100.
