NEMA 23 stepper motor, DQ542MA stepper motor driver, Labview connection.

[sherpaman]

Hello,

I am looking to use 2 NEMA stepper motors with 2 DQ432MA motor drivers on a linear actuators (2-axis). I would like to directly connect this to a Labview module to control it. I have NI 9478 module with DSUB and NI 9923. 

I just don't know of a way to connect the driver to the module.

Does anyone know of a way to do this?

Thanks,

Sherpaman

While the 9478 can output voltages from 5-50 V and most likely work with your drive, it will be challenging to implement this. You will have to manually create DAQmx tasks to send the appropriate signals to your drive. For motion applications, we typically recommend working with our motion hardware, even if you are using 3rd-party drives and motors: http://www.ni.com/white-paper/12127/en/.

Hello Brian,

I am planning on doing some simple image processing with some cameras. From that result, the motors will move to that specific location with further steps to follow.

I would like to avoid purchasing more hardware than what I already have. The motor driver has 6 outputs to control the direction and pulse, is there specific pins that will work on the (NI cDAQ-9178) + (NI 9478 with DSUB)?

The NI-9478 has 16 DO channels so that is not the issue. The challenging aspect will be the actual programming and understanding what signals are needed when to control your drive/motor.

Hello Brian,

I understand what you're saying. As for now it's fine for me to go in this direction.

I have attached a connection diagram from the motor + motordriver +  NI9923 + NI9478 + cDAQ9178 + 5VPowerSupply.

Would this connection be able to run the motors effectively?

Thank You,
