Homing Mode – Reference run
The objects listed here affect the execution of a drive module’s reference run. The reference run is
required for the positioning module in order to define the zero point of the axis.
See "Reference Run dialogue box" on page 75.
The type as well as the velocities and acceleration during the search for the zero point can be set.
For the execution of the reference run, the module has to be switched to the Homing Mode of
operation. Via the control word, the reference run is launched and, with the help of the status word,
the actual reference run status can be queried:
