Jog or continuous mode

The selection of jog or continuous mode is performed for the incremental procedure NC-

specifically for all axes via the machine data:

MD11300 $MN_JOG_INC_MODE_LEVELTRIGGRD (INC and REF in jog mode)

Jogging mode is the default setting.

Supplementary conditions

Indexing axis

Irrespective of the set increment value, an indexing axis traverses to the next indexing position

in the direction of travel after pressing the traversing key.

The electronic handwheels (accessories) can be used to simultaneously traverse selected

axes manually. The weighting of the handwheel graduations is dependent on the increment-

size weighting. Where coordinate offset or rotation is selected, manual travel can even be

performed in the transformed workpiece coordinate system.

Commissioning

For information on the commissioning of electronic handwheels, see Chapter "Start-up:

Handwheels (Page 724)".

JOG mode must be active. The user must also set the increment INC1, INC10, etc., which

applies to manual traversing using a handwheel. As with incremental travel, the required

machine function must be set at the PLC interface accordingly.

When the electronic handwheel is turned, the associated axis is traversed either in the positive

or negative direction depending on the direction of rotation.

If the axis is already being moved using the traversing keys, then manual traversing using the

handwheel is not possible.
