TEACH-IN PROCEDURE
The TEACH-IN function allows to set a start and end position by means of two external signals. The
analog signal will automatically adapted to the teached range.
The set output range (the overall information
to be output) is defined over the travel of
the specific application and is comprised
between the ends of the axis: the origin of
the axis, i.e. the point where you activate
either the START or the STOP input, and
the end of the axis, i.e. the point where you
activate the other input. For the positions
beyond the travel limits the current / voltage
signal level will be kept at the minimum /
maximum value of the selected range.
With ascending ramp, before the initial
position of the travel the encoder will
provide the minimum current / voltage
signal level of the output range (4
mA for AI1; 0 V for AV2). After the last
position of the travel the encoder will
provide the maximum current / voltage
signal level of the output range (20 mA
for AI1; 10 V for AV2).
On the contrary, with descending
ramp, before the initial position of the
travel the encoder will provide the
maximum current / voltage signal level
of the output range (20 mA for AI1; 10
V for AV2). After the last position of
the travel the encoder will provide the
minimum current / voltage signal level
of the output range (4 mA for AI1; 0 V
for AV2).
WARNING: It is mandatory to activate
the START input first and then the STOP
input.
