H1: Manual and handwheel travel
4.1 Overview
Manual traversing in the BCS and WCS
The user has the option of traversing axes in the basic coordinate system (BCS) or workpiece
coordinate system (WCS).
● Manual traversing in the BCS
Each axis can be traversed manually.
● Manual traversing in the WCS
Only the axes declared as geometry axes can be manually traversed in the WCS (channel-
specific). Any coordinate offsets or rotations that have been selected remain active.
Manual traversing of several axes
Several axes can be manually traversed at the same time in JOG mode. However, there is no
interpolatory relationship.
Control via the PLC interface
Manual traversing is controlled via the PLC interface.
See Chapter "Control via the PLC interface (Page 150)".
A separate PLC interface exists in each case for machine axes (axis-specific), geometry axes
(channel-specific), and orientation axes (channel-specific).
Parameter assignment (general)
For the manual traversing of axes, there are parameterizable properties, which are valid for
all JOG movements regardless of the traversing variant and the selected JOG function. These
are described under "Parameter assignment (general) (Page 151)".
Traversing variants
The following manual traversing variants are possible in JOG mode:
● Continuous traversing with the traversing keys of the machine control panel in jog or
continuous mode
See Chapter "Continuous manual travel (Page 157)".
● Incremental traversing with the traversing keys of the machine control panel in jog or
continuous mode
See Chapter "Incremental manual travel (Page 161)".
● Traversing of axes via electronic handwheels
See Chapter "Handwheel travel (Page 165)".
Manual traversing of the spindle
Spindles can also be traversed manually in JOG mode. Essentially, the same conditions apply
as for manual traversing of axes. Spindles can be traversed in JOG mode using the traversing
keys continuously or incrementally, in jog or continuous mode, or using the handwheel. The
function is selected and activated via the axis-/spindle-specific PLC interface in the same way
as for the machine axes. The axis-specific machine data also applies to the spindles.
