IS-A, IS-B IS-C
Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Rotation axis 1 deg/min 6 to 15000 6 to 12000
Set speed difference for the speed difference–based automatic corner
deceleration function when linear acceleration/deceleration after
interpolation used.
CAUTION
1 Even during dry run or external deceleration, the feedrate
difference is checked according to the F command in the
program.
2 If the G09 (exact stop) command is executed, an exact stop
is performed, and Automatic Corner Deceleration is not
executed.
3 This function is invalid for the feed per rotation command,
F1–digit feed command (M series), and rigid tapping
command, as well as in single block mode.
4 If the override is changed during operation, the feedrate
difference cannot be checked correctly.
This function is designed for high–speed precise machining. With this
function, the delay due to acceleration/deceleration and the delay in the
servo system which increase with the feedrate can be suppressed.
The tool can then follow specified path accurately and errors in the
machining profile can be reduced.
This function becomes effective when advanced preview control mode is
activated by G08P1 command.
In advanced preview control mode, the following functions are available:
(1)Linear acceleration/deceleration before interpolation for cutting feed
(2)Automatic corner deceleration function
