16.6 Absolute Position Detection Parameters

(PR) #2049 type
Select the absolute position zero point alignment method.
0: Not absolute position detection
1: Stopper method (push against mechanical stopper)
2: Marked point alignment method I (The grid point is the reference position.)
3: Dog-type (align with dog and near point detection switch)
4: Marked point alignment method II (The position with which the mark was aligned is the reference posi-
tion.)
9: Simple absolute position (Not absolute position detection, but the position when the power is turned off
is registered.)
#2050 absdir
Select the direction of the grid point immediately before the machine basic position (basic point of detector)
in the marked point alignment.
0: Positive direction
1: Negative direction
#2051 check
Set the tolerable range of travel distance (deviation distance) while the power is turned OFF.
If the difference of the positions when the power is turned OFF and when turned ON again is larger than this
value, an alarm will be output.
Set "0" to omit the check.
---Setting range---
0 to 99999.999 (mm)
#2054 clpush
Set the current limit value during the stopper operation in the dogless-type absolute position detection.
The setting value is the ratio of the current limit value to the rated current value.
---Setting range---
0 to 100 (%)
#2055 pushf
Set the feedrate for the automatic initial setting during stopper method.
---Setting range---
1 to 999 (mm/min)
#2056 aproch
Set the approach distance of the stopper when deciding the absolute position basic point with the stopper
method.
After using stopper once, the tool returns with this distance, and then use stopper again.
---Setting range---
0 to 999.999 (mm)
#2057 nrefp
Set the positive direction width where the near reference position signal is output.
When set to "0", the value is the same as #2218 SV018(PIT).
(Note) When "#1240 set12/bit2" is ON, a magnification (C: 10-fold, D: 100-fold, E:1000-fold) corresponding
to the input setting increment ("#1003 iunit") will be applied to the setting value.
---Setting range---
0 to 999.999 (mm)
(Input setting increment applied)
