Axis Specifications Parameters
II - 108
#2023 ozfmin Set up ATC speed lower limit
Set the minimum speed outside the soft limit range during the second to the fourth
reference position return.
---Setting range---
0 to 1000000 (mm/min)
#2024 synerr Allowable error
Set the maximum synchronization error, allowable at the synchronization error check, for
the primary axis.
When “0” is set, the error check will not be carried out.
---Setting range---
0 to 99999.999 (mm)
#2025 G28rap G28 rapid traverse rate
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)
#2026 G28crp G28 approach speed
Set the approach speed to the reference position.
(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)
#2027 G28sft Reference position shift distance
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) corresponding 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 direction (-)" 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)
#2028 grmask Grid mask amount
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)
#2029 grspc Grid interval
Grid space (#2029 grspc)
Set the distance between grids.
Normally, the ball screw pitch value (#2218 PIT) or the movement amount per motor
rotation is set as the grid space. To make the grid space smaller, set a divisor of the grid
space.
<Calculation method for movement amount per motor rotation>
(1) When linear feed mechanism is a ball screw:
The movement amount per motor rotation = the motor side gear ration / the machine
side gear ratio x the ball screw pitch
(2) When linear feed mechanism is a rack and pinion:
The movement amount per motor rotation = the motor side gear ration / the machine
side gear ratio x number of pinion gear teeth x the rack pitch
(3) For the rotary axis:
The movement angle per motor rotation = the motor side gear ration / the machine side
gear ratio x 360
---Setting range---
0.000 to 999.999 (mm)
