MD 1.2:Miniature Step Motor DriverView Data Sheet Motor compatibility; The MD 1.2 is a high performance 0 - 1.2 Amp RMS (1.7A peak) miniature stepper motor driver that is not only cost effective but powerful enough to handle the most rigorous motion control applications. Through proven stepper motor drive technology the MD 1.2 delivers the power effectively and efficiently (bipolar chopper drive with power reduction at stand still). At 0.275” above board height (horizontal mount) the MD 1.2 allows for easy integration into instrumentation, VME and European rack mount systems Our two mounting options allow for the most flexible use of valuable space in a modular or confined environment. Fully compatible with matching TMG stepper motor controller. Compatible with standard stepper motors (4,6 or 8 wire).

Shown with CY 5.4 motion control moduleEconomical Step Motor Driver The MS 2.0 is an extremely powerful stepper motor driver / translator unit capable of driving either bipolar or unipolar motors up to 2.8A peak per phase in Full, Half or Quad step (3200 s/rev). The step sequences are generated on-board, therefor, the MS 2.0 requires only digital step pulses and direction signal. No step software is required (onboard firmware). The MS 2.0 stepper motor driver features Switch-Mode, Bi-polar, Constant-Current technology (requiring no dropping resistors),adjustable maximum output current and Auto-park which reduces motor dissipation during non-step periods. Driver protection includes; over-temp, over-volts, over-current and reversed supplies. Top speed is limited only by motor type and stepper motor supply voltage. The MS 2.0 is used in the SID 2.0 single axis stepper motor controllers. Go to the Mechanical Specifications Page for dimensional specifications.
PLC version includes on-board or out-board adjustable oscillator, fail-safe limit loop and Auto-Park. Relay closure or switch to GND inputs (Run, Park and CW - CCW). Available with TST automatic proportional ramping.Used in PLC single axis stepper motor controllers. DSD Interface (MS Series) Stepper motor driverDSD version is a dial encoder interface which allows the accurate positioning of a stepper motor by rotating a dial. System includes power-reduction at standstill, over-speed protection, adjustable torque, and built in braking. System retains position during power-on; it will not “servo-crash”. Resolutions to 3200 steps of encoder dial.
