Defines the maximum shaft power in motoring mode,
ie. when power is being transferred from the motor to
the machinery.
The value is given in percent of nominal motor power.
Maximum shaft power in motoring mode.
Defines the maximum shaft power in generating mode,
ie. 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: With internal brake chopper, drive increases its
internal overvoltage control limit to enable higher
reliability in breaking.
Overvoltage control disabled.
