Moment of inertia estimator

Overview
From the load moment of inertia and the speed setpoint change, the converter calculates the
accelerating torque required for the motor. Via the speed controller precontrol, the accelerating
torque specifies the main percentage of the torque setpoint. The speed controller corrects
inaccuracies in the precontrol (feed-forward control).
