In a PMC sequence, activation of the master axis and polygon
synchronization axis must be turned on when the polygon
synchronization under way signal PSYN<Fn063.7> changes from 0 to
1.
In addition, while the polygon synchronization under way signal is 1,
prevent the activation of the master axis and polygon
synchronization axis from being turned off by, for example,
prohibiting the acceptance of spindle stop (for example M05) during
normal control.
when the polygon synchronization under way signal PSYN<Fn063.7>
changes from 1 to 0, basically turn off activation.
The NC stops at the G51.2 command block for entering the polygon
synchronization mode and does not proceed to the next block until the
spindle speed reaches the polygon synchronization speed.
- Method B
Even during the polygon synchronization mode, another M code or
the like is used to turn on or off activation of the spindle.
Or, even during the polygon synchronization mode, activation of the
spindle may be turned off.
For method B, set bit 7 of parameter No. 7603 (PST) to 1.
This parameter setting enables the polygon spindle stop signal
*PLSST<Gn038.0> and makes the NC proceed to the next block
without waiting for the spindle speed to reach the polygon
synchronization speed in the G51.2 command block for starting the
polygon synchronization mode.
In a PMC sequence, during the polygon synchronization mode (the
polygon synchronization under way signal PSYN<Fn063.7> is 1), set
the polygon spindle stop signal *PLSST<Gn038.0> to 1 after
confirming that activation of the master axis and polygon
synchronization axis is turned on.
When the polygon synchronization mode is not entered (the polygon
synchronization under way signal PSYN<Fn063.7> is 0), set the
polygon spindle stop signal *PLSST<Gn038.0> to 0.
When the polygon spindle stop signal *PLSST<Gn038.0> is changed
from 0 to 1 during the polygon synchronization mode, phase control is
performed after acceleration from the spindle stop state to the polygon
synchronization speed is performed.
