Stepper Motor Driver DQ420MA

Introduction:

  DQ**0MA  is a type  of two-phase hybrid stepping motor driver, The drive voltage of which is from *2VDC to *6VDC. It is designed for use with *-phase hybrid stepper motor of all kinds with *0mm to *2mm 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 DM**0A rund at high speed is also significantly higher than the 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:

High performance, low price

Average current control, *-phase sinusoidal output current drive

Supply voltage from *2VDC to *6VDC

Opto-isolated signal I/O

Overvoltage, under voltage, overcurrect, phase short circuit protection

8 channels subdivision and automatic idle-current reduction

8 channels output phase current setting

Offline command terminal

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

High start speed

High holding torque at high speed
