Manual traversing of geometry axes/orientation axes

Note
Transformation package, handling
In the JOG mode, using the "Handling transformation package" for SINUMERIK 840D sl, the
translation of geometry axes in several valid references systems can be set separately from
one another.

See also Chapter "Cartesian manual travel (optional) (Page 476)".
Simultaneous travel
Only one geometry axis can be traversed continuously or incrementally at one time using the
traversing keys. Where an attempt is made to traverse more than one geometry axis, alarm
20062 "Axis already active" is output. However, three geometry axes can be traversed
simultaneously using handwheels 1 to 3.
Transverse axis
If a geometry axis is defined as transverse axis (see MD20100 $MC_DIAMETER_AX_DEF)
and radius programming has been selected, the following applies:
● Continuous travel:
There are no differences when a transverse axis is traversed continuously.
● Incremental travel:
Only half the distance of the selected increment size is traversed. For example, with INC10
the axis only traverses 5 increments when the traversing key is pressed.
● Traversing with the handwheel:
As for incremental travel, with the handwheel only half the distance is traversed per
handwheel pulse.

PLC interface
For geometry axes/orientation axes, there is a separate PLC interface that contains the same
signals as the axis-specific PLC interface:
● Geometry axes:
DB21, ... DBB12-23 and
DB21, ... DBB40-56
● Orientation axes:
DB21, ... DBB320-331 and
DB21, ... DBB332-343
