Stationary state detection
A stationary state is detected by the Ethernet modules to which the handwheel is connected.
If a handwheel does not transfer any handwheel pulses for a defined period of time, the
module detects this to be a stationary state and transfers it to the NC/PLC interface:
NC/PLC interface signal Value Description
0 Handwheel 1 is operated DB10, DBX245.0
1 Handwheel 1 is stationary
0 Handwheel 2 is operated DB10, DBX245.1
1 Handwheel 2 is stationary
0 Handwheel 3 is operated DB10, DBX245.2
1 Handwheel 3 is stationary
By evaluating the signal, it is possible to reduce the overtravel of an axis traversed via the
handwheel, due to the handwheel pulses that have been collected in the control but not yet
transferred to the interpolator for traversing purposes. To do this, deletion of the distance-to-
go must be triggered for the relevant axis or in the channel when a stationary state is
detected:
DB31,... DBX2.2 = 1 (axial deletion of distance-to-go)
DB21,... DBX6.2 = 1 (channel-spec. deletion of distance-to-go)
3.11 Special features relating to manual and handwheel travel
3.11.1 Manual travel of geometry/orientation axes
Coordinate systems in JOG
In JOG mode, the user can also traverse the axes declared as geometry axes in the
workpiece coordinate system manually. Any coordinate offsets or rotations that have been
selected remain active.
Note
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.
