9. SPINDLE SPEED FUNCTION
868
CAUTION
1 When the spindle orientation function is to be used at the
same time
The spindle orientation function positions the spindle by
using sensors and the PMC, without being directly
controlled by the CNC.
The CNC has no direct control over this processing, instead
following the specifications of the spindle orientatio n
function being used.
2 When the spindle positioning function is to be used at the
same time
When the spindle positioning function is to be used together
with rigid tapping, rigid tapping mode must not be specified
in spindle indexing mode, and spindle indexing mode must
not be specified in rigid tapping mode. (Spindle positioning
and rigid tapping cannot be performed simultaneously for a
single spindle.)
This restriction does not apply, however, when
multi-- spindle control is applied; rigid tapping can be
performed using the second spindle.
The spindle positioning function is effective for the first
spindle only. This means that when spindle indexing is
performed with the first spindle, rigid tapping can be
specified with the second spindle.
3 When the Cs contouring control function for the serial
spindle is used together with the rigid tapping function, the
same motor is used for spindle rotation control, Cs
contouring control, and rigid tapping modes. The following
points must be noted:
(1)Whether to enter Cs contouring control mode or spindle
rotation control mode is selected by the CON (Cs
contouring control switch signal) signal; however, the
system can enter rigid tapping mode regardless of the
state of the CON signal. When the rigid tapping mode is
canceled the system enters spindle rotation control
mode or Cs contouring control mode according to the
state of the CON signal.
(2)Since the system can change to rigid tapping mode
directly from the Cs contouring contorl mode, use of the
Cs contouring control function enables the tapping tool
to be positioned before rigid tapping begins. Accurate
positioning is not guaranteed. If the rigid tapping cycle
executes gear change or output range changing,
positioning is valid.
