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”
Siemens S7-200 “Pulse Train Output” Setting
+ 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:
