6POSITIONING CONTROL

(1)The setting range of end point address for the both of circular interpolation axis and linear interpolation axis is (-231) to (231-1).

(2)The maximum arc radius on the circular interpolation plane is (231-1).

For example, the maximum arc radius for electronic gear 1:1 of unit [mm] is 214748364.7[µm].

(3)Set the command speed with the combined-speed for 2 axes circular interpolation axis.

(4)The command speed unit is specified in the parameter block.

(5)Set the number of pitches within the range of 0 to 999. If it is set outside the setting range, the servo program error [28] occurs, and cannot be started.

(6)All of the circular interpolation axis, linear axis and point address, command speed, radius (2 word data above) and number of pitches (1 word data) are set indirectly by D, W and #.
