Index length
This parameter allows to set the width of the Index pulse (0 pulse) expressed in
electrical degrees. Two options are available and selectable in the drop-down
box:
90° el (gated A, B)
and
180° el (gated A)
. Please note that the 0 pulse
having a width of 90 electrical degrees is synchronised with A and B pulses,
while the 0 pulse having a width of 180 electrical degrees is synchronised with
A pulse. See the Figure below.
Default = 90° el (gated A, B)
Min. value = 90° el (gated A, B); max. value = 180° el (gated A)
Index position
This encoder provides the zero signal (Index pulse) once per revolution as
relative positioning reference (home position, see the Figure above). In this way
a unique position can be identified at a well-known point in the 360° revolution
of the encoder shaft. This function allows to set the point in the revolution at
which the 0 pulse will be output. It is useful, for example, when you want the
zero position of the encoder and the mechanical zero position of the axis to
match. When you want to set the position of the 0 signal in the revolution you
must move the axis to the desired position, then press the
SET
button next to
this
Index position
item while the encoder and the mechanical assembly are in
stop.
