Parker Compumotor's E-AC is a low-cost, high-performance, high-reliability microstepping drive in a small package. The design of the E-AC is based on the design of our proven Zeta and OEM750 microstepping drives. It provides up to 3.5 Amps of current to the motor and accepts 120VAC direct-online power only. All step motors are subject to mid-range instability or oscillations. The E-AC incorporates an anti-resonance circuitry that aggressively and effectively suppresses these oscillations, thus taking advantage of the full capabilities of the step motor

  • Designed for use with motor inductance of 0.5 mH - 80 mH
  • 3-state current control allows the drive and motor to run cooler and more efficiently than 2-state drives
  • Selectable resolution up to 50,800 steps/rev
  • Auto standby reduces motor current (and heating) at rest
  • Provides 0.02 Amps to 3.5 Amps (peak)
  • 95 - 132VAC power supply input
  • Four predefined current waveforms to optimize smoothness
