B–63610EN/01
324
PLR The machine coordinates of a tool axis for polygon turning are:
0 : Rounded by the setting in parameter 7620.
1 : Rounded by 360° (or the setting in parameter No. 1260 when bit 0
(ROA) of parameter No. 1008 is set to 1).
RDG On the diagnosis screen No.476, for spindle–spindle polygon phase
command value (R), displays:
0 : The specified value (in the increment system for the rotation axis).
1 : The actual number of shift pulses.
NOTE
A phase command is specified in address R, in units of
degrees. For control, the actual shift amount is converted to
a number of pulses according to the conversion formula: 360
degrees = 4096 pulses. This parameter switches the display
of a specified value to that of a converted value.
PST The polygon spindle stop signal *PLSST (bit 0 of G038) is:
0 : Not used.
1 : Used.
7610

[Data type] Byte
[Valid data range] 1, 2, 3, . . . number of control axes
This parameter sets the control axis number of a rotation tool axis used
for polygon turning.
7620
