The DMC-4xx0 motion controllers can optionally be equipped with controllers for servo motors, voice coils, linear motors, torque motors or stepper motors. Motion controllers for 5-8 axes can be equipped with a maximum of 2 of the following controller units. Different variants allow a wide range of applications to be realized. With the D35x7, you can connect servo motors and stepper motors to one controller unit. It also makes no difference whether a 2-phase or 3-phase motor with brushes or without.
