B-63790EN/01 4.DESCRIPTION OF PARAMETERS
- 141 -
1850 Grid shift/reference position shift for each axis
NOTE
After this parameter has been set, the power must be
off turned off then back on for the setting to become
effective.
[Input type] Parameter input
[Data type] Integer axis
[Unit of data] detection unit
[Valid data range] 0 - 99999999
Specify the grid shift for each axis.
The grid position can be shifted by the amount specified in the
parameter to move the reference position. The grid shift must not
exceed the reference counter capacity (RC1x to RC4x (bits 0 to 3 of
parameter No. 1816) or parameter No. 1896).
This parameter is not used for a spindle positioning axis or Cs contour
control axis. For a spindle positioning axis for analog spindles,
parameter No.5980 is used. For a spindle positioning axis for serial
spindles, parameter No.3073 is used. For a Cs contour control axis,
parameter No.3135 is used.
NOTE
When SFD (bit 4 of parameter No. 1008) is set to 1, this
parameter indicates the "reference position shift
amount for each axis." In this case, the valid range is:
-999999999 to 999999999.
1851 Backlash compensation for each axis
[Input type] Parameter input
[Data type] Integer axis
[Unit of data] detection unit
[Valid data range] -9999 - 9999
Specify the backlash compensation for each axis.
When an axis moves in the direction opposite to the reference
position return direction after power-on, the first backlash
compensation is made.
For smooth backlash compensation, specify the backlash
compensation applied when the second phase backlash compensation
output is completed.
