2 , Stepper Motor Driver DQ420MA with 1.7A , 12-36V/128 Microstep

Introduction :

DQ420MA is a type of two-phase hybrid stepping motor driver, the drive voltage of which is from 12VDC to 36VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 20mm to 42mm outside diameter and less than 2.0A phase current. This circuit that it adopts is similar to the circuit of servo control which enables the motor to run smoothly almost without noise and vibration. Holding torque when DQ420MA driver runs at high speed is also significantly higher than other two-phase drivers, 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:

l High performance, low price

l Average current control, 2-phase sinusoidal output current drive

l Supply voltage from 12VDC to 36VDC

l Opto-isolated signal I/O

l Over-voltage, under voltage, over-current, phase short circuit protection

l 8 channels subdivision and automatic idle-current reduction

l 8 channels output phase current setting

l Offline command input terminal

l Motor torque is related to speed, but not related to step/revolution

l High start speed

l High holding torque at high speed
