Movement with an electronic handwheel
7.3.4 "Additive handwheel" mode
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 (inclined 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 general parameter ADIMPG (P176).
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.
