15.5 Sub Part System Control I

15.5 Sub Part System Control I
This function activates and operates any non-operating part system (sub part system) in the multi-part system.
Sub part system control I can be used in the same manner as calling subprogram in a non-operating part system. An auxiliary
axis machining program can be controlled in the sub part system by commanding Sub part system control I (G122) from the
main part system.
In the usage example below, the tool positioning starts to the machining start point at the same time (time T1) as the start of
gantry retract by using Sub part system control I (G145) in the flow from feeding the workpiece to moving to cut start position
in order to reduce the cycle time.
Select whether main part system or sub part system for each part system in Sub part system control I. When using a part
system as sub part system, by setting the operation mode to "Sub part system I operation mode" with the PLC signal and
commanding Sub part system control I (G122) from an operating part system, it is possible to activate the part system in the
sub part system I operation mode as sub part system.
