Product Family Overview

Parker / Compumotor A Series Microstepping Drive

  • DIP Switch Selectable Motor Resolutions
  • Automatic Standby Function Reduces Motor Heating When the Motor is Not Moving
  • High-Voltage Operation for Good High-Speed Torque
  • Microprocessor Controlled Microstepping Provides Smooth Operation


The A Drive is a bipolar, microstepping drive designed to drive two-phase permanent magnet hybrid step motors. The drive uses MOSFET technology to give high performance in a small package while providing short circuit protection, brownout protection, over-temperature protection, and a built-in power supply. The A Drive is compatible with all Compumotor indexers.

The A Drive requires no external power supply. It uses 120VAC directly for its power inputs. It comes in two versions (AL Low and AH High), which will produce up to 3A and 6A of current/phase respectively. Compumotor's motors are two phase hybrid motors (permanent magnet type). Four, six, or eight lead motors may be used with the internal phases connected for either parallel or series operation provided the motor's inductance does not drop below 20 mH.
