Stepper Drive DQ860MA

Introduction:

  DQ860MA  is a type  of two-phase hybrid stepping motor driver, the drive voltage of it is from 24VDC to 80VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 57mm to 110mm outside diameter and less than 7.8A phase current. This circuit that it adopts is similar to the circuit of servo control which enables the motor run smoothly almost without noise and vibration. Holding torque when DQ860MA run under high speed is also significantly higher than the other two-phase driver, what’s more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on.

Features:

High performance, low price

Average current control, 2-phase sinusoidal output current drive

Supply voltage from 24VDC to 80VDC

Opto-isolated signal I/O

Overvoltage, under voltage, overcurrent, phase short circuit protection

14 channels subdivision and automatic idle-current reduction
