Stepper Motor Driver DQ2722M

Product No.: N2010990326



 
Introduction
The DQ2722M is full digital 2 phase stepper driver based on DSP control. The drive voltage of which is
from 110V to 220VAC. It is designed for use with the 2 phase hybrid stepper motor of all kinds with 86mm
to 130mm outside diameter, regulated phase current 1.2A to 7.0A. The circuit that it adopts is similar to
the circuit of servo control which enables the motor run smoothly without noise and vibration. The highest
micro step is 60000ppr. It is widely used in middle and big size numerical control devices such as curving
machine, CNC machine, computer embroider machine, packing machine and etc.
 
 
Features
l  High performance, low price
l  16 channels constant angle, constant torque micro steps, highest micro step: 40000ppr
l  Highest response frequency: 200Kpps
l  Current of winding will be reduced by approximately 50% when no step pulse command is received for
   0.1 second
l  Opto-isolated signal I/O
l  Drive current is adjustable in 16 channels from 1.2A/phase to 7.0A/phase
l  Single power supply from 110V to 220VAC
l  Phase terminal memory function (motor phase terminal is memorized after input pulse train
   stopping 5s and it is recovered when stepper driver power on or signal MF changes from
   low level to high level)
