8-5-4 Origin Search Instructions
Execute the ORG(889) instruction in the ladder program to perform an origin search with the specified
parameters.
Precautions for Correct UsePrecautions for Correct Use
Limit Sensor Application
Create a program that can detect the limit sensor when performing an origin search.
The OUT instruction is used in the ladder program to write signals received from the CW limit
sensor and CCW limit sensor connected to normal inputs to the Auxiliary Area bits.
