Posted 6 Mar 2019 (edited) @SSK I think you need to seperate devices for Pulse Generator and Stepper Motor Drive. For Pulse Generator you can use any microcontroller board or PLC to create fix pulse for motor speed then connect it to stepper motor drive input that you can select any drive for suitable with stepper motor current. Example of simple pulse generator. https://www.yoycart.com/Product/38932026153/ http://www.99automation.com/pro37.htm Edited 6 Mar 2019 by Wasan Add example Share this post Link to post Share on other sites
