Allen Bradley MicroLogix 1100 “Servo Control” MR-J4-A Mitsubishi Tutorial

Written by

Hello friends!
Many people have messaged with the desire to instruct Allen Bradley MicroLogix PLC to generate pulses to control stepper and Servo motors because there is no tutorial on the net.

That’s why today will write a tutorial for you to use PLC MicroLogix 1100 “Pulse Train Output” to control Servo Mitsubishi MR-J4-A

MicroLogix 1100 & MR-J4-A “Wiring Diagram”

+ Use 2k2 Ohm resistor to reduce voltage 24VDC > 5VDC

+ Use any Relay to switch Output PNP > NPN

Mitsubishi MR-J4-A Driver Configuration

You can use the buttons available on the Driver or the MR-Configurator2 software to set the main engine parameters as follows:

In order for Servo to operate in the simplest way, please configure the following:

RSLogix 500 Funtion Files Setting uses Micrologix 1100 1763-L16BBB PLC that supports 2 pulse output ports with maximum speed of 40kHz

Note: Default OUT-Output parameter will be -1, we need to change it to 2 or 3 otherwise PLC will report an error

MicroLogix1100 PLC Programming

Below is the simplest and easiest program to control the Servo forward and reverse rotation as well as change the pulse speed.
