16.5 Zero Point Return Parameters
Set a rapid traverse rate for the dog type reference position return command.
This is not used for the distance-coded reference position detection.
---Setting range---
1 to 1000000 (mm/min)
Set up the speed of approach to the reference point in the reference point return command. This speed is
attained after the system stops with deceleration by dog detection.
In the distance-coded reference position detection, the set value will be applied from the start of reference
position establishment.
(Note) The G28 approach speed unit is (10°/min) only when using the Z-phase type encoder (#1226 aux10/
bit3=1) for the spindle/C-axis reference position return type. The same unit is used for both the micrometric
and sub-micrometric specifications.
---Setting range---
1 to 60000 (mm/min)
Set the distance from the electrical zero-point detection position to the reference position.
This is not used for the distance-coded reference position detection.
(Note 1) When "#1240 set12/bit2" is ON, a magnification (C: 10-fold, D: 100-fold and E: 1000-fold) corre-
sponding to the input setting unit ("#1003 iunit") will be applied to the setting value.
(Note 2) The sign of setting value is will be following: the direction of "#2030 dir (-) Reference position direc-
tion (-)" is plus, and the opposite direction is minus.
(Note 3) When set value is set to minus, the axis moves to electrical zero-point detection position at first and
then moves in opposite direction.
---Setting range---
-99.999 to +99.999 (mm)
Set the distance where the grid point will be ignored when near-point dog OFF signals are close to that grid
point during reference position return.
The grid mask is valid for one grid.
This is not used for the distance-coded reference position detection.
---Setting range---
0.000 to 99.999 (mm)
