13. Program Support Functions
Detailed description
(1) The high-speed high-accuracy control I / II can be used during computer link, tape, MDI, IC
card or memory operation.
(2) The override, maximum cutting speed clamp, single block operation, dry run, handle interrupt
and graphic trace are valid even during the high-speed high-accuracy control I / II modal.
(3) The machining speed may drop depending on the number of characters in one block.
(4) The high-speed high-accuracy control I / II function automatically turns the high-accuracy
control mode ON. For high-accuracy control function, refer to "13.14 High-accuracy control"
(5) Turn the tool radius compensation command ON and OFF during the high-speed
high-accuracy control I / II mode.
If the high-speed high-accuracy control I / II mode is turned OFF without turning the tool radius
compensation OFF, program error (P34) will occur.
(6) Turn the high-speed high-accuracy control I / II mode OFF before commanding data other than
the data listed above.
(7) When using the high-speed high-accuracy control II mode, set parameter "#1572 Cirorp" to "1"
to eliminate the speed fluctuation at the seams of the arc and straight line or arc and arc.
(8) Feedrate command (F) is clamped with the "#2110 Clamp (H-precision)" (Cutting feed clamp
speed for high-accuracy control mode) set with parameter.
(9) "#2109 Rapid (H-precision)" (Rapid traverse speed for high-accuracy control mode) set with
parameter will be valid for the rapid traverse speed.
(10) When "#2109 Rapid (H-precision)" is set to "0", movement is performed with "#2001 rapid"
(Rapid traverse rate) set with parameter. Also, when "#2110 Clamp (H-precision)" is set to "0",
clamp will be made with "#2002 clamp" (Cutting clamp speed) set with parameter.
Additional functions when high-speed high-accuracy control 2 mode is ON
(1) Fairing
If there is a protruding path (zigzagging path) shorter than the parameter setting values in the
machining program generated with a CAM, etc., this function can be used to eliminate the
protruding path smaller than the setting value so that the front and back paths are smoothly
connected. This function is valid only for continuous linear commands (G1).

#8029 Fairing L
If there is any protruding path after fairing, fairing is repeated.
