B–63010EN/02
392
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
Control axis number of tool rotation axis for polygon turning
[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
Movement of tool rotation axis per revolution
[Data type] 2–word
Increment system IS–A IS–B IS–C Unit
Rotation axis 0.01 0.001 0.0001
deg
[Valid data range] 1 to 9999999
This parameter sets the movement of a tool rotation axis per revolution.
7621
Maximum allowable speed for the tool rotation axis (polygon synchronization axis)
[Data type] Word
[Unit of data] rpm
[Valid data range] For polygonal turning using servo motors:
0 to 1.2 10
8
set value of the parameter No.7620
For polygon turning with two spindles:
Set a value between 0 and 32767, but which does not exceed the
maximum allowable speed, as determined by the performance of the
second spindle and other mechanical factors.
This parameter sets the maximum allowable speed of the tool rotation axis
(polygon synchronization axis).
If the speed of the tool rotation axis (polygon synchronization axis)
exceeds the specified maximum allowable speed during polygon turning,
the speed is clamped at the maximum allowable speed. When the speed
is clamped at a maximum allowable speed, however, synchronization
between the spindle and tool rotation axis (polygon synchronization axis)
is lost. And, when the speed is clamped, P/S alarm No.5018 is issued.
