dc stepper motor driver

Two phase hybrid stepping motor drive specification

Summarize

DQ420MA two-phase hybrid stepper motor drive which use DC 12 ~ 36V power supply is suit for two-phase hybrid stepper motor which drive voltage of 24V to 36V, current of less than 2.0A . Because the drive is controlled by all-digital current loop subdivision, the torque of motor ripples slightly and the motor runs smoothly at low speed, produces low noise and vibration. When it is high-speed that can be output a relatively high torque and high positioning accuracy. It widely used in the engraving machine, CNC machine tools, packaging machinery and transmission equipment.

The main feature:

- Constant current control, two phase sinusoidal current drive output

- DC 12 ~ 36 V power supply

- Photoelectric isolation signal input/output

- Over voltage, under voltage, over current, and short circuit protection function

- Eight file segmentation and automatic half current function

- Eight file output phase current settings

- Off-line function

- Start high speed

- High speed torque

2,Control signal port

2.1,Control signal definition

PUL: The input port of stepping pulse signal

DIR: The input port of stepper direction signal

+5V:The input port of common positive signal

ENA: The input port of offline enable signal

Offline enable signal is active to reset drive malfunction, prohibit any effective pulse .Output power element is closed and motor have no holdingtorque.

3,Installation

The surrounding should have 20mm of space and cannot be placed next to other heat-generating equipment. We must avoid dust, oil mist, corrosive gas, too much humidity and strong vibration places.
