How to control 2 phases step motor with Mitsubishi Q00J CPU?

trongbim · Nov 21, 2018

Hello everyone,

I'm a newbie to PLC who wanna use Q00J CPU with Output module QY40P for generating high-speed pulses to control 2 phase step motor. But I can't find out any function like PLSY, PLSR. I think there are some differences from Q series which I didn't get it.

Anybody know how to use it? I appreciate your help.

For Q00J cannot use PLSY you need to change your CPU module to at least Q00UCPU to use PLSY command.

Thank sir, it's so informative. Have you ever used Q00J for position control?

For Q00JCPU you should use QD70P4 or QD75P1N for position control to send pulse to stepping motor drive that I think it overprice for only control stepping motor.Maybe change CPU are suitable than add position module unless you have many stepping motor that use position module are reasonably.

I have a QD75P2 but it seems to be hard for newbie as me. Could you give me some wiring and programming instructions or documents, sir?
