OMD18 Stepper Drive & Controller


The OMD18 is an advanced stepper motor drive and motion controller in one.  Through a simple RS485 communications interface you can control a stepper motor with exceptional control and accuracy. Selectable acceleration ramps at velocities up to 2M steps/sec. Selectable step size resolution from full up to 1/16 fractional step. Its small design is compatible to mount on the back of a stepper motor, and includes a hole in the center so the shaft of a linear actuator motor can pass through when mounted on the motor.



  • Advanced control through RS485 interface

  • Velocity = 0 to 2M steps per second

  • Step resolutions include full, 1/2, 1/4, 1/8 & 1/16

  • Exceptional accuracy: +/- 0% position, 2% velocity

  • Single supply voltage +8V to +30V

  • 0 to 1.7 amp phase current

  • Center mounting hole for linear actuator stepper motors

  • Easy wiring with screw-terminal connectors

  • No heat-sink required

  • Motor current set through the interface
