Home search.
When the axes are position-Sercos; during parameter matching, the CNC sends the value
of parameter REFSHIFT to the drive so it takes it into account; this way the CNC coordinate
and that of the drive will be the same.
Peculiarities of home search for Mechatrolink axes.
The servo carries out the home search and the home switch must be wired to the servo. The
homing procedure follows this sequence. Refer to the documentation of the device for further
detail.
1 When homing starts, the axis moves in the homing direction (set by the parameters of
the servo) at the feedrate set by parameter REFFEED1.
2 When the axis presses the home switch, it switches to approach feedrate 1 (set by the
parameters of the servo).
3 When the axis releases the home switch and receives the home signal, it switches to
approach feedrate 2 (set by the parameters of the servo).
4 Once the axis has traveled the final positioning distance (set by the parameters of the
servo), the servo concludes the home search.
Peculiarities of home search for spindles, tandem system and
analog axes.
Peculiarities of home search for spindles.
Parameter REFINI determines whether the CNC homes the spindle in its first movement or
not. The CNC takes this parameter into account only when parameters NPULSES y
NPULSES2 have been set with a value other than 0.
If the spindle has been homed, the spindle orientation in M19 does not force a new home
search.
