GH series GH3A5/GH5A4/GH8A5/GH130/GH170

Product Features

Designed and produced by a competetive market demand, the EP3 series Multifunctional AC Servo Driver adopts an intelligent power module (IPM) and advanced control algorithms, which achieve precise control on torque, speed, and position using either Digital (Step and Direction) or Analog (±10V) Input Command. Based on the EP2 series, the EP3 sports more advanced features such as USB Interface for configuring operations via PC software, Modbus/TCP for communication over ethernet, and built-in internal PLC functionality. These drives have advantage of strong overload capacity, fast response, as well as a feedback mode of 2500 line incremental encoder (10000 Quadrature) or 17 bit absolute encoder, which supports 16 bit current sampling and 16 bit external analog sampling accuracy. The front operation display panel provides real-time monitoring and an interface for configuring operational adjustments.


This series includes two sets of model variants with differing input power ratings, namely 3-phase 220V GL models and 3-phase 380V GH models.


Notable Features

  • High-Speed opto-isolated step/direction, CCW/CW, and A/B phase control input modes.
  • Differential Step/Direction signals to eliminate signal corruption due to noise.
  • Optional command pulse filters cut off extreme acceleration/decceleration commands.
  • Automatic error detection mechanisms such as overvoltage, overcurrent, overload, overspeed, abnormal encoder etc.
  • Resonance inhibition.
  • Built-in PLC functionality.
  • Modbus/TCP and USB Interface
  • Adjustable Encoder Output gain
  • 2500 Counts/Rev Encoder with 10000 Counts/Rev in Quadrature.
