NI myDAQ wiring connection with Microstep Driver

[Curious_Mind]

Hi,

I am trying to control a stepper motor using Microstep Driver ST-M5045.  I am using NI myDAQ.

I want to control the motor direction (clockwise/ anticlockwise). But I am not sure how to do the wiring with my DAQ. Which port of DAQ should be connected with which port of Microstep driver? The Driver link is here : https://www.sainsmart.com/products/cnc-4-5a-micro-stepping-stepper-motor-driver .

Any kind of help is really appreciated. Please help me with proper connection diagram

I'm not familiar with the myDAQ, but I have used similar stepper drivers in the past.

PUL- DIR- and ENA- can all be connected to the DAQ Gnd.

DIR+ and ENA+ should be connected to standard digital output pins on the DAQ.

PUL+ should be connected to a counter output.

Changing HIGH / LOW on ENA+ will enable or disable the driver (you will have to check which way around this is).

Changing HIGH / LOW on DIR+ will change the rotation direction.

You need to generate a pulse train on the PUL+ pin. Each pulse will be one (micro)step on of the stepper.

Thanks. Seems like this will work
