5.2.4 "Additive handwheel" mode
With manual intervention or additive handwheel, it is possible to move the axes manually while a
program is being executed. 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 individual handwheel associated with the axis. Only one additive handwheel may be enabled
at a time; the CNC will only attend to the first enabled handwheel.

(A) Position of the tool while in execution.
(B) Position of the tool after a manual intervention.
This feature must be managed from the PLC. This feature is usually activated and
deactivated by means of an external push-button or a key configured for that purpose.
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.
If the additive handwheel is enabled for a coordinate transformation G46 (incline axis), 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 axis machine parameter ADIMPG.
Considerations to the additive handwheel.
The movement with the additive handwheel on the master axis is also applied to the slave axis when
using axes that are gantry.
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.
