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：

16 channels constant angle, constant torque micro steps, highest micro step: 60000ppr

Highest response frequency: 200Kpps

Current of winding will be reduced by approximately 50% when no step pulse command is received for 0.1 second

Opto-isolated signal I/O

Drive current is adjustable in 16 channels from 1.2A/phase to 7.0A/phase

Single power supply from 110V to 220VAC

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)
