Abstract

A motor drive utilizes redundant current feedback to monitor force being produced by a motor and to provide safe limited force producing operation of the motor. A first set of current sensors provides a first current measurement, and a second set of current sensors provides a second current measurement. The two current measurements are provided to two diverse force producing calculations, where each force producing calculation provides a value of the force produced by the motor. The motor drive compares the output of the two algorithms to each other. If the output of the two force producing calculations is the same, within an acceptable band, the controller continues operating as commanded. If the output of the two force producing calculations differs beyond the acceptable band, then the controller may generate a fault message provided back to a central controller, stop operation of the motor, or a combination thereof.
