(2) Parameters
(a) Additional axis address
For additional axes, address characters can be selected from A, B, C, U, V, or W by the
setting for parameters pm1201 and pm1202. The address characters to be used to express
basic axes are restricted to X, Y, and Z.
(b) Segment data conversion start and end codes
In this manual, “HON” and “HOF” are used for the start and end codes. However, the
codes are not restricted to these and can be specified in the following range.
• Three alphanumerics (beginning with an alphabet)
• Those which are not reserved for use in the NC language such as HON, HOF, and
G05.
Start designation code: Parameters pm4161, pm4162, and pm4163
End designation code: Parameters pm4164, pm4165, and pm4166
(c) Segment data type
For parameter pm4167, always set “4”.
(d) Selecting the conversion mode
For parameter pm4160, always set “1”.
(e) Number of axes used for high-speed cutting
Set the number of axes for parameter pm 1200. The setting range is from 3 to 5;
“3” for 3 axes, “4” for 4 axes, and “5” for 5 axes.
(f) Accuracy at corners
Use parameter pm4800 for setting set acceleration/deceleration to be applied for cutting at
corners.
If “0” is set, setting of “500 (mm/sec 2 )” is assumed.
(g) Acceleration/deceleration
User parameter pm4810 for setting acceleration/deceleration to be applied for high-speed
cutting with exception of corners.
If “0” is set, setting of “500 (mm/sec2)” is assumed.
(h) Allowable acceleration for circular arc blocks
Use parameter pm4823 for setting the allowable limit of acceleration for circular arc
blocks where high-speed cutting is executed.
If “0” is set, setting of “500 (mrn/sec2)” is assumed.
(i) Shape offset coefficient
