Appendix 1 Explanation of Parameters
【#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.
Axis speed
The grid mask is valid for one grid.
---Setting range---
0 to 65535 (μm)
Even for the specifications in sub-micrometric system, set up the value in units of μm.
【#2029】 grspc Grid interval
Set a detector's grid interval.
Normally, set a value equal to the ball screw pitch. However, if the detector grid interval is different
from the screw pitch because a linear scale etc. is used, set the detector's grid interval.
Use its divisors, if you wish to reduce the grid interval.
You can set the minimum setting increment to be 0.001mm, by using a negative value.
Example) Setting value
1 -> 1.000 mm (°)
-1 -> 0.001 mm (°)
Even when the specification is in sub-micrometric system, 0.001 mm is the minimum setting
increment.
---Setting range---
-32767 to 999(mm)
【#2030(PR)】 dir (-) Reference position direction (-)
Select which side of the near-point dog the reference position is established.
0: Positive direction
1: Negative direction
Directions in which reference position is established as viewed from the near-point dog
- direction
- direction
Reference position
【#2031】 noref Axis without reference position
Select whether the reference position is provided for the axis.
0: Reference position is provided. (Normal controlled axis)
1: No reference position is provided.
When "1" is set, reference position return is not required before automatic operation starts.
