The sign of the reference switch search speed (P MAXRPM) corresponds
to the sign of the speed command value that applies when positioning is
initiated (control input RUN 1->0). If the speed command value at the
time has to be switched to zero by the controller, then positive or negative
speed can be set for locating the reference switch signal.
The reference switch signal from the spindle must be connected to the
EXT POS control input.
The angle a
min
is the minimum ≥° of the spindle reference switch. The
maximum reference point detection error is given by the angle a
min
and
the hysteresis of the spindle reference switch.
The affect of the hysteresis can be eliminated, if the reference switch
signal is always searched for in the same direction. In this case, the
speed command value must always have the same sign when
positioning is initiated.
•a
min
depends on the search speed of the reference point on the spindle.
Search speed is the value of parameter P-MAXRPM.
