Specification :

1) Input: AC110V-220V
2) Output: 1.2A-7.0A RMS
3) Mating stepper motor: 2 phase, 86-130mm
4) competitive price, high performance stepper motor driver

DQ2722M is 2 phase stepper motor driver based on DSP control. It is new fully digital driver configured by advanced DSP chip and unique control circuit. The voltage is AC110V-220V and rated current is under 7.0A. The mating stepper motor is 2 phase hybrid stepper motor with 86-130mm outer diameter. The internal driver circuit is similar to that of servo control theory, which makes the motor run smoothly, almost no vibration and noise. The max positioning accuracy can be up to 40, 000 steps per revolution. DQ2722M is widely used in large/ medium NC equipment with high resolution like engraving machines, medium CNC machine tools, computer embroidery machine, packaging machinery and etc.

Features:

1) High performance and competitive price.

2) 16-channel selectable resolution, max 40, 000 steps/ R.

3) Max response frequency up to 200Kpps.

4) Coil current will be automatically reduced to 1/ 2 of pre-set current when stepping pulse stops over 100ms.

5) Optical isolating signals I/ O.

6) Driving current can be adjusted from 1.2A/ phase to 7.0A/ phase through the 16 channels.

7) Single power supply ( AC110V-220V)

8) Phase memory function ( Note: The driver can memorize the motor phase automatically when the input stops over 3 seconds. And it also can recover the phase automatically when it is re-powered or MF signals changes from low level to high level. )

9) DQ series stepper motor driver have different Algorithms for high and low speed, so motor runs more stably and smoothly at high and low speed.
