- 152 -
1867 Threshold value for scale data conversion (common to all axes)
[Data type] 2-word
[Unit of data]
Input increment IS-A IS-B IS-C Unit
Rotary axis 0.01 0.001 0.0001 deg
[Valid data range] 0 to 99999999
If scale data is greater than the setting of this parameter, data for one
rotation is subtracted from the scale data to ensure scale data
continuity within the movable range. Be sure to set the scale data
(angle from a discontinuity point) of a position outside the movable
range as a threshold value. This parameter is common to all axes. This
parameter is invalid for an axis with a nonzero value set in parameter
No. 1868 used for each axis.
NOTE
1 When this parameter is set, the power must be
turned off before operation is continued.
2 This parameter is valid only for those axes with bit
3 (SCR) of parameter No. 1817 set to 1.
3 If the setting of this parameter is modified, perform
a reference position establishment operation again.
4 With the T series, this parameter is valid for a
rotary encoder with distance-coded reference
marks (detection circuit C).
