Abstract
Examples include a method for controlling a variable speed drive of an electric motor. The variable speed drive is connected to a torque sensor for sensing a torque supplied by the electric motor. The method includes performing, by the electric motor, a predetermined torque sequence. The method also includes measuring, by the torque sensor, a measured torque sequence corresponding to the predetermined torque sequence, and comparing the predetermined torque sequence and the measured torque sequence. As a result of the comparison, one or more torque sensor transfer function parameters are determined.
