12. ABSOLUTE POSITION DETECTION SYSTEM
12 - 20
12.6.3 Home position setting
(1) Dog type home position return
Preset a home position return creep speed at which the machine will not be given impact.
On detection of a zero pulse, CR is turned from off to on. At the same time, the servo amplifier clears the
droop pulses, comes to a sudden stop, and stores the stop position into the non-volatile memory as the
home position absolute position data.
CR should be turned on after it has been confirmed 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 1,000,000 times.
