- 404 -
8184
Coordinates of the reference point of an axis on the coordinate system of
another axis under composite control
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm, inch, degree (input unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] 9 digit of minimum unit of data (refer to standard parameter setting
table (A) )
(When the increment system is IS-B, -999999.999 to +999999.999)
This parameter specifies the coordinates of the reference point of an
axis on the coordinate system of another axis under composite control.
The parameter is validated when MPMx of bit 4 parameter No.8162 is
set to 1.

X2-axis

(∆X1m, ∆Z1m) are the coordinates of the reference point of path 2 on
the workpiece coordinate system of path 1. (∆X2m, ∆Z2m) are the
coordinates of the reference point of path 1 on the workpiece
coordinate system of path 2.
∆X1m is specified for the parameter No. 8184x of path 1 and ∆X2m
for the parameter No. 8184x of path 2.
If bit 4 (MPMx) of parameter No.8162 is set to 1 when composite
control is started, the workpiece coordinate system satisfying the
following conditions is specified:
X1 = (Value specified for the X-axis of path 1) ± (Machine coordinate
of X2)
Plus when parameter MCDx (bit 6 of No.8162) of path 1 is set to
0
Minus when parameter MCDx (bit 6 of No.8162) of path 1 is set
to 1
