1)DQ: BS Fully Digital Economical Series
2)3: Matching 3-phase 86-130mm micro stepper motor
3)7: Output 1.2-7.0A RMS
4)22: Input AC110-220V
5)M: Standard version
DQ3722M is 3-phase stepper motor driver based on advanced DSP control. It is new fully digital driver configured by DSP control chip and unique circuit. The driving voltage is AC110-220V, adapting to all models of 3-phase hybrid stepper motor whose current is below 7.0A and with 57-130mm outer diameter. The internal driver circuit is similar to that of servo control, which makes the motor run smoothly, almost no vibration and noise. The max positioning accuracy can be up to 60,000 pulse/R. It is widely applied in large/medium NC equipment with high resolution like engraving machines, medium CNC machine, packaging machinery and etc.
Features
● High performance and competitive price
● 16-switch selectable resolution, max resolution 60,000 pulse/R
● Max response frequency up to 500Kpps
● Coil current will be automatically reduced to 1/2 of pre-set current when stepper 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 also it can recover the phase automatically when it is re-powered or MF signals changes from low level to high level. )
