■Data set type homing

Move the machine to the position where the home position is to be set by performing the manual operation such as JOG

operation. When CR is on for longer than 20 ms, the stop position is stored into the non-volatile memory as the home position

absolute position data.

CR during servo-on should be turned on after checking that INP has turned on. If this condition is not satisfied, [AL. 096 Home

position setting warning] occurs. If homing is performed correctly, the alarm is automatically canceled.

The number of homing times is limited to 100000.

Homing can be performed during the servo-off.
