MicroStepping Drives


High performance microstepping drive and power supply with high torque stepper motors.


With the original SureStep drive you just set a few DIP switches, hook-up a motor and connect to a PLC (or other controller) – it couldn’t be easier, and it’s a great fit for many simple applications. However, some customers asked for more functionality, and higher current capability. So, we've introduced two new Advanced Programmable SureStep stepper drives. With software-selectable resolution up to 51,200 steps per revolution for smoother, more accurate motion and power capability up to 10 A/phase, these stepper drives take SureStep to the next level.

  • Pulses (or "step" and "direction" signals) from the DirectLOGIC family of PLCs or other indexers and motion controllers are "translated" by the microstepping drive into precise movement of the stepping motor shaft.
  • The SureStep stepping motors use 2-phase technology with 200 full steps per revolution or 1.8 per full step. Older type stepping motor drives, which operate stepping motors in full step mode, can result in stalling or lost motion due to potential problems with low speed mechanical vibration (usually between 100 to 200 RPM).
  • To minimize this vibration problem, the SureStep microstepping drive uses advanced microstepping technology with selectable step sizes of 400 steps per revolution ( 2), 1,000 steps per revolution ( 5), 2,000 steps per revolution ( 10), and 10,000 steps per revolution ( 50).
  • A SureStep power supply is available which can operate at least two complete SureStep stepping systems and includes an auxiliary +5 VDC supply to facilitate DirectLOGIC PLCs and stepping driver interfaces.
