(1) The setting range of end point relative address for the both of circular interpolation
axis and linear interpolation axis is 0 to
(2
31
-1).
The travel direction is set by the sign (+/ -) of the travel value, as follows:
• Positive travel value .............Positioning control to forward direction
(Address increase direction)
• Negative travel value............Positioning control to reverse direction
(Address decrease direction)
(2) The maximum arc radius on the circular interpolation plane is 2
31
-1.
For example, the maximum arc radius for electronic gear 1:1 of unit [mm] is
214748364.7[
µm].
