Description: This item includes: 1PC DQ420MA with 1.7A peak current ,12-36VDC ,128 Microstep For Nema17 motors 1. Introduction: DQ420MA is a type of two-phase hybrid stepping motor driver, the drive voltage of which is from 12VDC to 36VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 20mm to 42mm outside diameter and less than 2.0A phase current. This circuit that it adopts is similar to the circuit of servo control which enables the motor to run smoothly almost without noise and vibration. Holding torque when DQ420MA driver runs at high speed is also significantly higher than other two-phase drivers, what’s more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on. Features: l High performance, low price l Average current control, 2-phase sinusoidal output current drive l Supply voltage from 12VDC to 36VDC l Opto-isolated signal I/O l Over-voltage, under voltage, over-current, phase short circuit protection l 8 channels subdivision and automatic idle-current reduction l 8 channels output phase current setting l Offline command input terminal l Motor torque is related to speed, but not related to step/revolution l High start speed l High holding torque at high speed Electrical specification: Input voltage 12-36VDC Input current ＜ 2A Output current 0.44A- 2.83A Consumption Consumption：40W； Temperature Working Temperature -10～45℃； Stocking Temperature -40℃～70℃ Humidity No condensation, no water droplets gas Prohibition of combustible gases and conductive dust weight 70G 1. Pins assignments and description: 1) Connector Pins Configurations Pin Function Details PUL +,PUL- Pulse signal, PUL+ is the positive end of pulses input pin PUL- is the negative end of pulse input pin DIR+,DIR- DIR signal: DIR+ is the positive end of direction input pin DIR- is the negative end of direction input pin ENA+ Enable signal: ENA+ is the positive end of direction input pin. This signal is used for enabling/disabling the driver. High level for enabling the driver and low level for disabling the driver. ENA- ENA- is the negative end of direction input pin.
