The FM 453 is an intelligent, three-channel module designed for a wide range of positioning tasks using servo and/or stepper motors. It can be used for simple point-to-point positioning tasks as well as for complex traverse profiles with the most stringent demands for dynamic response, accuracy, and velocity.
