4.2.4.4 Increment mode - selection
Before traversing the axes using the direction keys, select the appropriate
incremental weighting on the associated machine control panel.
This key (INC variable) is used for traversing an increment previously set:
For setting the variable increment, activate this softkey and enter the value you
require in the input field.
Press the INPUT key for entering the value in the "Incremental weighting for
INC variable" window.
Use the direction keys to traverse the axes incrementally in JOG mode. In the
case of milling machine controls, select the axis first.
You can reselect this function by pressing the active incremental weighting
key; JOG mode is automatically effective.
The selected increment function is displayed in the mode field.
The direction keys can act in two different ways:
• Modal
• Non-modal.
Modal means that the axis is always traversed by one increment (corresponding
to the setting 1, 10, 100, 1000, 10000 mm) regardless of whether the key is
pressed briefly or held down.
Non-modal means that the axis is traversed only as long as the key is held
down and the set increment is reached. When the key is released, the traversing
movement is stopped - even if the set increment has not yet been reached!
If the key is pressed again, the increment is traversed anew.
