Control 3 phase stepper motor

Projects General Guidance
1

I have a big problem to command the direction of motor

  1. I am using Arduino UNO
  2. I use a Accelnet ADP as the driver (I have attached the pic and datasheet below)
  3. The driver interface with the Arduino UNO by rs-232
  4. 3 phase stepper motor is connected to the driver (U, V, W connected to the driver)

I don’t know how to write the code to control the direction of the motor

Does it work with the downloadable PC software?

If the driver board is using RS232 voltages you will need a MAX232 converter to adapt to the TTL serial voltages of the Arduino, RS232 voltages won't be understood and may damage an Arduino.

To Start get the Arduino cookbook and read it. Also on line there are many videos etc showing the Arduino and how to do what you want. This additional information will go a long way in phrasing your question and getting your problem solved.

You're going to have to find a document that describes the serial communication protocol; it may be this:

From the look of it, communications are non-trivial. It's going to take a bit to figure it out unless you can find example code.

This is not an Arduino project, and especially not one for a beginner in Arduino. Use the professional software that is already available.
