30.30 Overvoltage control Enables the overvoltage control of the intermediate DC link.
Fast braking of a high inertia load causes the voltage to rise
to the overvoltage control limit. To prevent the DC voltage
from exceeding the limit, the overvoltage controller
automatically decreases the braking torque.
Note:
If the drive is equipped with a brake chopper and
resistor, or a regenerative supply unit, the controller must be
disabled.
