Manual and Handwheel Travel (H1)
8.1 General characteristics of traversing in JOG
Handwheel jogging
The axes can also be traversed via the handwheel in MCS or WCS. Incremental traversing
(INC...) must be set to evaluate the handwheel pulses (see Section "Handwheel traversal in
JOG").
Traversing the geometry axes
If workpieces whose workpiece coordinate system is not parallel to the machine coordinate
system are being machined (inclined clamping, programmed rotation active in the contour),
traversing can be done along the axes of the workpiece coordinate system via the traverse
keys or handwheel. In the stopped state, switch from the operating mode AUTO to JOG and
traverse a geometry axis instead of a machine axis. Depending on the active rotation of the
workpiece coordinate system, between one and three machine axes move.
If a machine axis is traversed, this cannot also be moved via the traverse keys of a geometry
axis. The traversing motion of the machine axis must first have been completed - otherwise
alarm 20062 "Axis already active" is output. Two geometry axes can be traversed
simultaneously with the handwheels 1 and 2.
Note
A separate, channel-specific PLC interface supplies geometry axes.
Transverse axis in "turning" technology
A geometry axis is defined as a transverse axis. If radius programming (DIAMOF) is selected
instead of diameter programming (DIAMON), the following must be noted when traversing in
JOG:
● Continuous traversing: There are no differences when a transverse axis is traversed
● Incremental traversing: Only half the distance of the selected increment size is traversed.
● Traversing with the handwheel: As for incremental travel, with the handwheel only half
Spindle manual travel
The spindle can also be traversed manually in the JOG mode. Essentially the same
conditions apply as for manual traverse of machine axes. With JOG, the spindle can be
traversed via the traverse keys/ IS "continuous" or "INC...". The mode is selected and
activated via the axis-/spindle-specific PLC interface as for the axes.
Spindle manual travel is possible in positioning mode (spindle in position control) or in open-
loop control mode. The parameter set (machine data) of the current gear stage applies.
