8.MULTI-PATH CONTROL B-63943EN-1/02
- 946 -
(2) Parameter setting
- To superimpose the move command for the Z1 (master) axis
on that of the Z2 (slave) axis, set parameter No. 8186z of
path 2 to "102".
- Because the plus directions of the Z1 (master) and Z2
(slave) axes are opposite from each other, perform
superimposed control with a mirror image applied. To do
this, set parameter OMRz (No. 8162#3) of path 2 to "1".
(3) Signal operation
- To start superimposed movement along the Z1 (master) axis
and the Z2 (slave) axis, set signal G1190#1 OVLS2 to "1".
- To cancel superimpose, set signal G1190#1 OVLS2 to "0".
- When an emergency stop, NC reset, or alarm occurs, set
G1190#1 OVLS2 to "0".
- Set signals other than G1190#1 OVLS2 to "0".

(5) Caution
CAUTION
If performing constant surface speed control, you
must determine the spindle command in which path
is currently effective to spindle S1.
