6. INTERPOLATION FUNCTION
507
CAUTION
6 During polygon synchronization mode, speed change and
phase adjustment are performed each time the spindle
speed is changed. Therefore, this mode cannot be used
together with a function that causes continuous spindle
speed change (such as G96 constant surface speed
control)
7 During the polygon synchronization mode, the rotation ratio
between the master axis and polygon synchronization axis
is controlled with priority. Therefore, the difference between
the master axis speed and S command value may become
larger than during ordinary spindle control. (The masteraxis
speed may be up to 2 rpm lower than specified.)
NOTE
1 During the polygon synchronization mode, phase control is
performed in the least command increment of 36/4096 =
0.08789...(degrees) in reference to the one-- rotation signal
for each spindle. Actually, a command value out of a range
from 0 to 359.999... is meaningless because the relative
phase is controlled within one rotation of each spindle.
Howe ver, this function does not limit the R command value
and the CNC converts the R command value to a value
below 360 degrees.
2 The G51.2 command during conversational function is
equivalent to the G50.2 command. (The system does not
enter the polygon synchronization mode. If it is already in
the polygon synchronization mode, release it using a G51.2
command.)
