Description
Defines the maximum shaft power in generating mode, i.e.,
when power is being transferred from the machinery to the
motor. The value is given in percent of nominal motor power.
Note: Do not set this parameter to 0% in an attempt to
prevent reverse rotation. In an open-loop application, that is
likely to prevent the motor from stopping altogether. To
prevent reverse rotation, use the speed/frequency limits in
this parameter group, or parameters 20.23/20.24.
Maximum shaft power in generating mode.
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.
Overvoltage control disabled.
Overvoltage control enabled.
Enables the undervoltage control of the intermediate DC
link. If the DC voltage drops due to input power cut off, the
undervoltage controller will automatically decrease the
motor torque in order to keep the voltage above the lower
limit. By decreasing the motor torque, the inertia of the load
will cause regeneration back to the drive, keeping the DC
link charged and preventing an undervoltage trip until the
motor coasts to a stop. This will act as a power-loss ride-
through functionality in systems with high inertia, such as a
centrifuge or a fan.
Undervoltage control disabled.
Undervoltage control enabled.
Settings that define the behavior of the drive upon fault
situations.
