1. AXIS CONTROL

N1120 ······· N2120 ········ Machining under
control independent of
the other path
WARNING
When using constant surface speed control, be careful
about which path has the spindle command that is effective
for spindle S1.
NOTE
The speed of spindle S1 (feedback pulses from the position
coder) is specified for both paths 1 and 2.
S Synchronous control and composite control were described so far. In
reality, however, it is possible to perform more than one set of
synchronous control and/or composite control selectively or
simultaneously. For this purpose, specify all necessary parameters
and select which synchronous control or composite control to be
performed using the appropriate signals. However, be careful not to
perform more than one set of synchronous control or composite
control for one axis at one time.
S Usually, it is possible to specify only one pair of axes for synchronous
control and one pair for composite control. If it is necessary to specify
more than one pair, specify so in a parameter with a program, using the
programmable parameter input function (G10). This must be done
when the related axes are not under synchronous or composite control.
(Example) Changing the parameter so that the Z2–axis is synchronized
with the Y1–axis
(To set parameter No. 8180z of path 2 to “4”, run the
following program in path 2.)
N0200
········
N0210 G10 L50 ; Begins parameter setting.
N0220 N8180 P2 R4 ; Sets parameter No. 8180z
to “4”.
N0230 G11 ; Terminates parameter
setting.
N0240
········
The blocks with G10 to G11 must be run when the Z2– or
Y1–axis is not under synchronous or composite control.
