14. ABSOLUTE POSITION DETECTION SYSTEM
(2) Data set type home position return
Move the machine to the position where the home position is to be set by performing manual operation
such as jog operation. When the home position setting (CR) is on for longer than 20ms, the stop position is
stored into the non-volatile memory as the home position ABS data.
When the servo on, set home position setting (CR) to ON after confirming that the in-position (INP) is ON. If
this condition is not satisfied, the home position setting warning (AL.96) 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 1,000,000 times.
