5.4.4 Checking the Operation of the Near Home Switch and Home Switch

Procedure:
1. Using forced operation of the home input and near home input, check to make sure the
operation display LEDs on the positioning unit light. At the same time, using programming
tools, monitor the X_6 and X_7 flag (When X_6 is ON, the home input is properly
done. When X_7 is ON, the near home input is properly done.), and check LEDs light.
2. Input the home return program, and actually carry out a home return to check if near home
input produces deceleration.
Points to check
The input valid logic for the home input and near home input is determined by the control codes of the
program.
3. Using repeated JOG operation and home return operation, check to make sure the table stops
properly at the home position, with no offset.
Points to check
There may be times when near home input, the home input position, and the return speed cause
offset from the home position.
4. If the table does not stop precisely at the home position, either change the position of the near
home input, or reduce the home return speed, so that the table stops precisely at the home
position.
