Written by plc247.com

Hello friends!
In the previous article, plc247.com showed you how to use PLC MicroLogix 1400 to control Stepping Motor, today I will continue to guide you to control Servo Motor Yaskawa Sigma 7

Basically, the control method is the same as Stepping Motor, plc247.co still uses a simple program so that you can easily familiarize yourself with the PLC.

Note: Model MicroLogix 1400 1766-L32BXB Support Pulse Train Output (1766-L32BXBA same)

+ R= 2K2Ω: Reduce voltage from 24VDC to 5VDC

Yaskawa Sigma 7 Parameters Setting

Here are the main parameters of Yaskawa Sigma 7 that we need to install (Use SigmaWin software, download link below the article)

+ Pn200.0: Reference Pulse Form
plc247.com 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

+ Pn000.1: Control Method Selection

MicroLogix 1400 “Pulse Output” Configuration

Note: It is necessary to set “OUT – Output” to be 2,3,4 (corresponding to Out2, Out3, Out4), then the PLC can generate pulses to control the Servo Motor. The default setting is (-1) if you don’t change it, the program will get Error.
