Read Absolute Encoder Data from Yaskawa Sigma II Drive (LabVIEW FPGA)

VERSION 2 Published

REQUIREMENTS:
Application Software: LabVIEW Base Development System
Add-on Software: LabVIEW FPGA Module 8.5
Development Topic: FPGAs

 

The Sigma II servo drive made by Yaskawa Electric is able to read absolute positions from compatible absolute encoders. This information can be relayed externally via a serial data line on the drive.

 

The attached PDF details the connections and format of the data. To summarize, serial data is received on the PS line. The SEN signal must be set high to reset and thus synchronize with the continuous serial stream.

 

This code provides a serial implementation on LabVIEW FPGA for reading the absolute encoder position and alarm data from the drive.
