Hi! I have to connect a stepper motor with a driver to an Arduino Mega, and I need your help. I have never worked with a stepper motor with a drive, and wanted to double-check if I can directly connect to an Arduino. Let me know what you guys think!
Stepper Motor with Driver: McMaster-Carr
You will need an operating manual for that motor/driver, and a heavy duty industrial power supply. Post links to those for advice.
You connect the driver to the Arduino -and- a power supply capable of driving the motor’s voltage & current.
Then, using enable , direction and step signals you control the motor.
There are tons of examples and documents on this subject. There are no shortcuts, you have to put in the work.
You also need to know the actual torque needed in order to select the proper voltage for the motor.
Hi, @justbelieve
Is this related to this post?
Hi! I am completely new to this field and wanted advice on my setup. I have a motor controller with an RS-485 Interface that I'm hoping to connect to an Arduino Mega to control the speed of the motor. Also, I have two motors that run alternatively, so I have two motor drivers and two RS-485s. I attached my circuit and code below, but I am not too sure if it's correct. If anyone can check it out and lmk that would be great!
[circuit (15)]
Code so far:

That is unkown as McMaster-Carr does not provide enough information about the electrical interface to the motor to know if that is possible.
