6. INTERPOLATION FUNCTION
725
[Classification] Output signal
[Function] Informs the PMC that the system is in the polygon synchronization mode.
[Output condition] The polygon synchronization mode command (G51.2) sets this signal to
logical “1”. It stays at “1” as long as the system is in the polygon synchro-
nization mode. It is turned to “0” when the polygon synchronization
mode is cleared (G50.2 command or a reset). It stays at “0” when the sys-
tem is not in the polygon synchronization mode.
NOTE
The same address is used for this signal in both polygonal
turning (using the servo axis) and the polygonal turning with
two spindles.
[Classification] Input signal
[Function] This function is enabled when bit 7 (PST) of parameter No. 7603 = 1. This
signal is used to stop the spindle during the polygonal turning mode with
two spindles.
“0” = polygon spindle stop
“1” = polygon spindle operable
During the polygonal turning mode with two spindles, the spindles are
controlled with a positional loop set up. When issuing a spindle stop
command (like M05) to deenergize the spindle, it is necessary to specify S
= 0 using *SSTP<G00296#6>. Otherwise the motion command remains
effective even after the spindle is deenergized. This error accumulates and
causes a dangerous behavior of the spindle when it is energized again.
This signal is intended to inhibit distribution of the S command to the
spindle if it cannot be set to 0 while the spindle is deenergized. In such a
case, the signal should be used in step with the energizing state of the
polygon spindle.
