PLC Keyence “Servo Control” Yaskawa Sigma 7 Tutorial

Written by

Hello friends!
Servo Yaskawa is one of the widely used Servo Motors in the world “Yaskawa Sigma 7” is a popular model of the company with very good quality and durability.

Today would like to write a tutorial for you to use PLC Keyence KV3000, KV5000, KV5500 to control Yaskawa Sigma 7 motor by generating pulses

PLC Keyence & Yaskawa Servo “Connection Diagram”

Use a 2k2Ω resistor if you connect pins 7, 11 of Yaskawa Sigma7 to +24VDC. Or directly connect pins 7, 11 to pin 20 of the PLC without using resistors

Yaskawa Sigma 7 Parameters Setting

To be able to control Yaskawa Sigma 7 by pulse generator method from PLC, we need to set the basic parameters as below

  • Pn200.0: Reference Pulse Form uses 1 pulse control mode (Pulse + Direction)
    >>> Select “0: Sign + Pulse, positive logic”
  • Pn200.3: Filter Selection
    >>> Select “1: Uses reference input filter for open collector signal (to 200kpps)”
  • Pn20E + Pn210 + Pn212
    Three parameter is used to set the number of pulses for 1 revolution of the motor selects the control parameter as “1PLS = 10um”, Ball screw leed = 5mm

>>> Pn20E: 16,777,216 / Pn210: 500

  • Pn000.1: Control Method Selection

PLC Keyence Pulse Train Output Setting

PLC Keyence KV 3000, KV5000, KV 5500 have built-in 2 pulse generator ports, in this project using X-axis . You can install it like the picture below

+ Note: Select Position No.1 as ABS (Absolute) Control type

PLC Keyence Pulse Output Example

+ Servo ON/OFF Control

+ Emergency Stop Pulse Output

+ Zero Return Process

+ Axis Jog Process

+ Position Control Command
