Many people have messaged plc247.com 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 plc247.com 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
plc247.com 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.
