Explanation
Sets the origin search method.
Setting
0 Origin at power ON
The motor position at powering ON is automatically defined as the
origin.
If an origin search is performed in this mode, the starting position of
the origin search is defined as an origin.
1 Limit reversal
Input of the limit input signal during an origin search reverses the
operation.
After starting an origin search in the origin search start direction at the
origin search feed rate, the speed is changed to the origin search
approach speed at the rise of the origin proximity input signal (Nor-
mally Open contact). At the rise of the origin determine signal after
the fall of the origin proximity input signal, the speed changes to the
origin search creep speed to travel for the final interval and finally an
origin is determined.
2 2-level speed in 1 direction
Origin search is executed only in 1 direction.
After starting an origin search in the phase-Z detection direction at the
origin search approach speed, the speed changes to the origin
search creep speed at the rise of the origin determine signal input to
travel for the final interval and an origin is determined. Inputting the
limit input signal before inputting the origin determine input signal
activates the alarm.
3 3-level speed in 1 direction
Origin search is executed only in 1 direction.After starting an origin
search in the phase-Z detection direction at the origin search feed
rate, the speed is changed to the origin search approach speed at the
rise of the origin proximity input signal (Normally Open contact). At
the rise of the origin determine signal input after the fall of the origin
proximity signal input, the speed changes to the origin search creep
speed to travel for the final interval and finally an origin is determined.
Inputting the limit input signal before inputting the origin proximity
input signal activates the alarm.

gin (page 490).
