Quick Details

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)

Current Setting

Stepper driver working current is set by DIP-1 switches.

Subdivision (Micro Step) Setting

The subdivision (micro step) is set by DIP switches D1 to D4 of DIP-2, 16 channels in total. D5 and D6

are used to set the driver function.

Subdivision (micro step)	400	500	600	800	1000	1200	2000	3000
D1	ON	ON	ON	ON	ON	ON	ON	ON
D2	ON	ON	ON	ON	OFF	OFF	OFF	OFF
D3	ON	ON	OFF	OFF	ON	ON	OFF	OFF
D4	ON	OFF	ON	OFF	ON	OFF	ON	OFF
D5	ON, double pulse: PU is positive pulse signal, DR is negative pulse signal
D5	OFF, single pulse: PU is pulse signal, DR is direction signal
D6	Self detect switch (OFF: accept external pulse, ON: the driver send pulse to make the motor work at the speed of 30r/m)
