NOTE
•
Every time you change the value in the
Round Loop
setting, then you
are required to enter new values also in
Teach Minimum
,
Teach
Maximum and SSI Offset registers.
•
Using the ROUND LOOP function it is also possible to change the
counting direction of the encoder, by setting the
Direction
bit
correspondingly.
•
After any action concerning the
Round Loop
and
Direction
settings,
new entries of Teach Minimum , Teach Maximum and SSI Offset
registers become necessary.

This register allows to select the format of the analogue outputs as shown in
the Figure hereafter:

The range of the encoder where the analogue output should move between
minimum and maximum output must be set next to the parameters
Teach
Minimum
and
Teach Maximum
respectively (see on page 41). If
Output Mode
= 0 (-10V … +10V) you must set a value that is half the maximum resolution of
the encoder next to the
Teach Minimum
parameter (value has to be always
positive); you must set the maximum resolution of the encoder next to the
Teach Maximum
parameter. In all other cases (
Output Mode
= 1, 2 or 3) set 0
