Contour Handwheel/Path Default Using Handwheel (Optional For Sinumerik 840D) - Siemens SINUMERIK 840D sl Function Manual

4.7 Contour handwheel/path default using handwheel (optional for
SINUMERIK 840D)
Function
When the function is activated, the feedrate of path and synchronized axes can be controlled
via a handwheel in AUTOMATIC and MDI modes.
Function response
MD11346 $MN_HANDWH_TRUE_DISTANCE
The response below can be set for the contour handwheel using above machine data
(handwheel path or velocity specification):
● Path definition
● Velocity specification
Feedrate
The feedrate in mm/min is dependent on:
● The number of pulses supplied by the selected handwheel within one period
● The handwheel's pulse weighting set via machine data
● The activated increment (INC1, 10, 100, etc.)
● The path weighting of an increment
The feedrate is not dependent on:
● The programmed feedrate mode (mm/min, mm/rev.)
● The programmed feedrate (resultant velocity can be higher)
● The rapid-traverse rate for G0 blocks
● The override (position 0% is effective, i.e., zero speed)

4.7 Contour handwheel/path default using handwheel (optional for SINUMERIK 840D)

Limiting the velocity to the maximum permissible value causes the axes to overtravel. The
path defined by the handwheel is traversed and no pulses are lost.
The handwheel only defines the traverse velocity. As soon as the handwheel stops, the
axes stop too. The movement is braked immediately if no pulses are supplied by the
handwheel in one interpolation cycle, thus preventing overtravel by the axes. The
handwheel pulses do not supply a path default.
