Under common conditions, the position of a stepper motor is deterministic and predictable, but what about when the motor does not behave as expected? Many devices demand real-world, real-time feedback from the motor for added safety and monitoring purposes. Closed-loop operation of motors can furthermore increase the efficiency and overall performance of your application, for example by reducing the current when the motor is on standby and increasing the current under load conditions. As such, closed-loop control increases the system’s control reliability and flexibility.
