17 Manual intervention with additive handwheel
With manual intervention or additive handwheel, it is possible to move
the axes manually while a program is being executed. To do this, once
this option is activated, use the handwheel to make a movement to be
added to the one resulting from the automatic execution. This
movement will be applied as if it were another zero offset.
The general handwheel will be used as the additive handwheel. If
there is no general handwheel, use the handwheel associated with the
axis.
The intervention with an additive handwheel is only possible in
execution mode, even while the program is interrupted. However, it is
not allowed in the tool inspection mode.
The additive handwheel cannot be enabled while TCP (G48) is active.
However, the additive handwheel is enabled for a coordinate
transformation G46 (inclined axis) or G49 (incline plane) where the
handwheel movements are applied to the machining operation even
if they are not shown on the graphics screen.
The offset caused by the additive handwheel stays active after
disabling the handwheel and it is reset to zero after a home search.
The offset stays active or is reset after an M02 or M30 and after an
emergency or a reset depending on the setting of g.m.p. ADIMPG
(P172).
Considerations
• The movement with the additive handwheel on the master axis is
also applied to the slave axis when using axes that are gantry,
slaved or synchronized by PLC.
• When testing the software limits during block preparation, it checks
the theoretical coordinate ignoring the additional movement of the
additive handwheel.
• The mirror image by PLC is not applied to the additive handwheel
movement.
