SMAX - SSI and analogue
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 SMAX-AI1-...; 10 V for SMAX-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 SMAX-AI1-...; 0 V for SMAX-AV2-...).
So for instance, if you have a SMAX-AV2-... sensor (its output range is 0-10 V)
and you program an ascending ramp, then the encoder will provide a fixed
voltage level of 0 V for the positions before the origin of the travel (i.e. the point
where you activate the
START 
input); a voltage level increasing from 0 V
(origin of the travel, position 0) to 10 V (end of the travel) for the 1024 positions
of the axis; a fixed voltage level of 10 V for the positions after the last point of
the travel (i.e. the point where you activate the
STOP

input).
NOTE
For any further information on the START  and STOP

input signals refer to
the “5.2 Signals description” section on page 21.
5.3.1 TEACH-IN procedure
WARNING
It is mandatory to activate the
START
 input first and then the
STOP

input.
To programme the encoder using the TEACH-IN procedure act as follows. The
steps to define a ramp with increasing output values are described hereinafter;
