Motoring mode Motor operation mode in which the motor rotates the load and takes power from
the drive DC link (normal operation).
Generating mode Motor operation mode in which the motor decelerates (brakes) the load and
generates energy back to the drive DC link.
This effect is also seen when the load is held at a fixed speed, but the
mechanical load is trying to “pull” the motor to a higher speed, sometimes
referred to as overhauling. Overhauling loads return energy to the DC link as
well.
