12. ABSOLUTE POSITION DETECTION SYSTEM
12 - 21
(2) Data set type home position return
POINT
Never make home position setting during command operation or servo motor
rotation. It may cause home position sift.
It is possible to execute data set type home position return during the servo off.
Move the machine to the position where the home position is to be set by performing 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.
When the servo on, set CR to on after confirming that INP is on. If this condition is not satisfied, [AL. 96
Home position setting warning] will occur, but that warning will be reset automatically by making home
position return correctly.
The number of home position setting times is limited to 100,000 times.
