High Performance Motion Control with Built in Drive

The Dover Motion DMCM high performance controller can drive both stepper and servo motors and has built in I/O support for coordinated motion and high speed triggering.


Print Datasheet


The Dover Motion Control Module (DMCM) provides versatile high performance motion control with a built in drive that is capable of running 3 phase servo, 1 phase servo, or 4 wire stepper motors at various current output levels. It includes interpolation for use with either analog or digital encoders.

Design Features

The DMCM – Dover Motion Control Module is a versatile controller and servo drive capable of powering stepper or servo motors and provides many advanced capabilities. It is the only drive in its class that allows selectable motor current scaling to ensure optimal current resolution for optimal stability and closed loop control performance. A single power source is used for both motor and logic supply, with on board intelligence that allows the motor power to be disconnected while leaving the logic powered on.

A high speed Trigger On Position can be configured to allow a laser or camera to be triggered using the exact position of the stage. This can be setup as a constant incremental trigger at a fixed distance, or can be configured using a stage position look up table to trigger at different intervals.

The DMCM also includes an interpolated encoder feedback digital quadrature output. This signal can also be used as a master signal sent to a slave axis for coordinated motion.

Fast multi-axis communication can be implemented using RS-485, CAN or SPI. RS-485 is also available for multi-axis applications.
