Manual of 2-phase hybrid stepper motor driver DQ542MA

Introduction:

DQ542MA is a type of two-phase hybrid stepping motor driver, the drive voltage of which is

from 18VDC to 50VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds

with 42mm to 86mm outside diameter and less than 4.0A 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 DQ542MA 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, 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 18VDC to 50VDC

Opto-isolated signal I/O
