3 PCStepper motor driver DQ2722MA 110-220VAC
stepper motor driver:DQ2722MA
Introduction
The DQ2722MAis 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 with86mmto130mmoutside diameter, regulated phase current1.0Ato 9.8A. 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.
Feature
- High performance, low price
- 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 1.0A/phase to 9.8A/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)
