NOTE
1. When the two spindles seize the same workpiece, a spindle may be fixed at
a position slightly displaced from the specified position because the two
spindles are mechanically connected. In this case, an excessively high
current can flow because the velocity loop integral function attempts to
return the spindle to the specified position. To prevent this, turn on (set to
1) the velocity loop integral control signal INTGA to disable the velocity
loop integral function if the two spindles are mechanically connected.
2. When the velocity integral control signal INTGA is turned on (set to 1), the
velocity loop integral function is disabled. So, an increased synchronization
error can occur. When the two spindles do not seize the same workpiece,
turn off (set to 0) the velocity integral signal INTGA to enable the velocity
loop integral function.
Spindle synchronous control ready signal PSYFN
[Classification] Input signal
[Function] Specify to start spindle synchronous control on spindle synchronous control
by program command.
On spindle synchronous control by program command (G51.8), if spindle
synchronous control commanded signal (PSYON) is turned on and any
setting like spindle rotational direction on PMC are finished, specify this
signal to start spindle synchronous control.
[Operation] If this signal turned on after G51.8 commanded, spindle synchronous
control will be started.
When PSYON signal turned off, set this signal to 0.
Note
This signal is effective only for spindle synchronous control by program.
