13.5 Proximity Switch Method Orientation
Proximity switch method orientation performs the positioning with the proximity switch position attached to the spindle end as
spindle zero point.
There are two methods for proximity switch method orientation: standard method where the servo turns OFF once before the
speed decelerates to Z phase detection speed and high-speed method where the servo does not turn OFF.
 Standard method
The servo turns OFF once before the speed is decelerated to the Z phase detection speed.

 High-speed method
The servo does not turn OFF and the speed keeps moving to the Z phase detection speed.

By enabling the high-speed proximity switch method orientation (parameter "#3128 ori_spec/bit1" = "1"), the high-speed
function is valid.
The high-speed function is valid only when the proximity switch detection method (parameter "#3106 zrn_typ/bitF" = "1") is
valid.
