S7 1200 “Servo Control” Yaskawa Sigma 7 Tutorial

Written by

Hello friends!
Yaskawa Sigma Series Servo Motor is one of the most popular and used Models in the world. Excellent quality, high durability and competitive price are the advantages of the Yaskawa Sigma 7 Servo Motor.

Today will guide you to use PLC Siemens S7 1200 Pulse Generator control Servo Motor Yaskawa Sigma7. Siemens S7-1200 can control both “NPN” or “PNP” Servo Motor

S7-1200 & Yaskawa Sigma 7 “Wiring Diagram”

+ Use 2k2Ω Resistor to reduce voltage 24VDC > 5VDC

+ Use 1 Intermediate Relay to convert PNP to NP for “Servo-ON” signal

I/O Address

+ Input

  • I0.4: Low Limit Switch Sensor
  • I0.5: High Limit Switch Sensor
  • I0.6: Homing Sensor

+ Output

  • Q0.0: Pulse Output
  • Q0.1: Direction Output
  • Q0.2: Servo ON

Yaskawa Sigma.7 Parameters Setting

We can use SigmaWin+ software or install it directly with the button on the Driver to set the parameters for Yaskawa Sigma 7, below are the main parameters we need to setting

  • 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
    3 This parameter is used to set the number of pulses for 1 revolution of the motor

Below is an example table to install some basic applications

  • Pn000.1: Control Method Selection
