Polygon synchronization under way signal PSYN<Fn063#7>
[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
synchronization 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 system 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.
Polygon spindle speed arrival signal PSAR<Fn063#2>
[Classification] Output signal
[Function] Informs the PMC that the spindle has reached its constant-speed for
polygon synchronization during polygonal turning with two spindles.
[Output condition] During polygon synchronization mode with two spindles, whether the
constant-speed is reached for polygon synchronization is output as
shown below:
"0" = not reached (during phase change or acceleration/deceleration
under way)
"1" = reached
During the polygon synchronization mode, this signal becomes logical
"1" when the speed of each spindle reaches the acceptable level
specified in parameter No. 7631 and remains there for a period
specified in parameter No. 7632.
If the speed of either spindle goes off the acceptable level, or a change
is made to the S command, the signal returns to logical "0" and begins
monitoring the above condition.
When this signal is "0", the specified speed ratio and phase are not
guaranteed for polygonal turning. If the signal is confirmed before
actual turning is started, however, the operation is more efficient than
when a dwell command (like G04) is used to allow wait time.
Polygon master axis not arrival signal PSE1<Fn063#0>
Polygon synchronization axis not arrival signal PSE2<Fn063#1>
[Classification] Output signal
[Function] Informs the PMC whether the actual speed of each spindle has reached
the specified speed during polygonal turning mode with two spindles.
[Output condition] During the polygonal synchronization mode with two spindles,
whether each spindle has reached the polygon synchronization speed
is output as shown below:
"0" = reached
"1" = not reached (during phase change or acceleration/deceleration
under way)
During the polygonal synchronization mode with two spindles, this
signal becomes logical "1" when the speed of master axis and polygon
