Siemens S7-200 “Servo Control” Mitsubishi MR-J4-A Tutorial

Written by plc247.com

Hello friends!
Mitsubishi MR-J4 is one of the most commonly used Servo Motor in the world, good quality and durability are its advantages. Today plc247.com will guide you to control it with Siemens S7-200 PLC in the easiest way.

We need to use Siemens S7-200 PLC model with Transistor Output (DC/DC/DC) to support high-speed pulse generation to control Servo Motor.

Siemens S7-200 & MR-J4-A Servo “Wiring Diagram”

Below is a simple connection diagram between PLC Siemens S7-200 and Mitsubishi MR-J4-A Servo, you can use more function pins after you have mastered the control.

Note: Need to use more resistors to reduce voltage from 24VDC to 5VDC at 2 pins “Pulse and Direction”

+ S7-200 PWM/PTO Control Registers

+ S7-200 PWM/PTO Configuration

Mitsubishi MR-J4-A Parameters Setting

We need to install the following main parameters for Mitsubishi MR-J4-A Servo (use MR-Configurator 2 software for easy installation)

  • PA1: Servo control mode selection > Set to “1000” to select the position control mode.
  • PA6/7: CMX/CDV: Input pulse gain ratio. Used to correct the change of the number of pulses / revolutions when issuing a command from the PLC to the Servo. The default is 1/1, which corresponds to 131072 pulses / revolution
  • PA13.PLSS: Selection of control pulse types: Default is 0100, change the following two factors to select pulse input type. Please see the table below to choose the appropriate control method:

You can Copy the same parameters as Project as below

  • hello, good morning. How are you?

    My machine has a Siemens servo motor and it had a problem. I have the Mitsubishi drive and servo. What would I need to change in the ladder program? Or should I just change the driver and servo and parameterize it?

    Thanks
