15. ABSOLUTE POSITION DETECTION SYSTEM
(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 when 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 to turn the motor shaft more than one revolution. 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.
The home position setting (CR) should be turned on after it has been confirmed that the in-position
(D01 or 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.
