Machining With The Handwheels; Setting The Increment Weighting For The Handwheel; Machining With Axis Direction Switch - Siemens SINUMERIK 808D User Manual

4.2.2

Machining with the handwheels

Functionality
The handwheels for the X and Z axes are not mechanically connected to the feed screws. Electronic pulse generators
mounted on the handwheels generate the information needed by the controller to execute the required traversing movement.
The handwheels are only active when the axis direction switch is in the zero position or the individual axis control keys are
disabled.
The distance traversed per handwheel pulse depends on the increment weighting setting.
Note
If the handwheel increment weighting is set to "0" or if the feedrate override weighting is in the "0" position, the handwheels
are disabled.
4.2.3

Setting the increment weighting for the handwheel

Functionality
Set the increment weighting from the Increment weighting machine control panel.
If you are unable to adjust the increment weighing, it will be because the controller's internal mode is incompatible with this
process.
Press the above hardkey once to resolve the problem.
NOTICE
Set increment weighing carefully
An incorrect increment weighting setting can result in damage to the workpiece, tool and machine.
4.2.4

Machining with axis direction switch

Functionality
You can move the axes in the desired direction by changing over the axis direction switch.
The feedrate at which an axis is traversed depends on the settings in the input fields for machining technology data.
The axis feedrate is also influenced by the feedrate override weighting setting and, depending on the option selected in the
input fields for machining technology data (revolutional feed/cutting speed), by the spindle override weighting.
If the above hardkey is also pressed, the axis is moved at the maximum possible speed, unless the feedrate override
weighting setting is used to specify a different value.
