EL7-EC Series AC Servo Drives - 220V

EL7-EC Series AC servo products 220V are high performance AC digital servo which is designed for

position/velocity/torque high accurate control with power rating ranging up to 2kW which provides a

perfect solution for different applications with easy tuning process.

EL7-EC series AC servo drives are using the latest Digital Signal Processing (DSP) chip and Intelligent

Power Module (IPM) with compact components integration and great reliability. Using the best PID

calculation for Pulse Width Modulation (PWM) control, our EL7-EC series products are the one to beat in

this product category.
