Specifications

 

Stepper Digital Driver DQ2722M AC110-220V 7.0A 200 Microsteps Matching Nema 42 stepper motor CNC Laser Mill

 

 

DQ2722M is 2-phase stepping motor driver based on advanced DSP control algorithm. It is fully digital stepping motor driver of new generation. The driving voltage range is AC110-220V, adapting to all models of 2-phase hybrid stepping motor whose current is below 7.0A and 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 pulse/R. DQ2722M is widely used in large/medium NC equipment with high resolution like engraving machines, medium CNC machine, computer embroidery machine, packaging machinery and etc.

 

Features

 

High performance and competitive price
16-switch selectable resolution, max resolution 40,000 pulse/R
Max response frequency up to 500Kpps
Coil current will be automatically reduced to 1/2 of pre-set current when stepping pulse stops over 100ms.
Optical isolating signals I/O
Driving current can be adjusted from 1.2A/phase to 7.0A/phase through the 16 channels.
Single power supply (Voltage range: AC110-220V)
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. )

Caution

1. The input voltage can not exceed AC220V.

2. Input control signal is 5V, current-limiting resistance should be connected when it is over 5V

3. The input of pulse trailing edge is valid

4. ALM lights and the driver stops working when the driver temperature is over 75C. Until the temperature falls to 50C, it will restart to work after powered-up. The heat sink is needed when overheat occurs

5. ALM lights if it is short circuit, please check motor leads and eliminate other short faults, and then repower up to restore

6. ALM lights if the motor does not connect well with the driver, please check motor leads and repower up to restore
