Phase-Z (Phase-C) detection direction
Note
Setting
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 established.
Inputting the limit input signal before inputting the origin proximity
input signal activates the alarm.
For details of origin search operations, see SECTION 8 Establishing the Ori-
gin (Page 532).
Name
Origin search start direction
Setting range
00000000 to 00000001 Hex
00
(0 to 1)
Explanation
Sets the origin search start direction for the origin search method 1 (Limit
reversal).
0: Same as the phase-Z detection direction
1: Opposite to the phase-Z detection direction
The setting of this parameter is ignored in other origin search methods.
Name
Phase-Z (Phase-C) detection
direction
Setting range
00000000 to 00000001 Hex
00
(0 to 1)
Explanation
Sets the phase-Z (phase-C) detection direction for origin search methods 1, 2,
and 3 (other than 0:Origin at power ON).
0: + direction
1: − direction
The setting of this parameter is ignored in the origin search method 0: Origin
at power ON.
