For a crane/hoist, an elevator
application, as lifted up and down at
controlled speeds, its direction of
rotation is frequently reversed. In such
cases, the load can be started
smoothly, by adding load torque into
the torque reference equivalent to the
additional torque, when starting
acceleration after releasing the brake.
