The orientation of the sensing
head over the magnetic tape must
be compulsorily observed and is
always indicated in the technical
documentation.
Orientation
Please note that the orientation
does not affect the operation of
an incremental encoder: the encoder
works properly regardless of
the mounting direction of the measuring
system parts.
However check the cable outlet and operate the sensor accordingly to have a standard
counting direction. In an incremental encoder the standard counting direction is achieved
when the sensor moves according to the installation instructions so that the rising
edge of the signal A leads the rising edge of the signal B; and on the contrary, the reverse
counting direction is achieved when the sensor moves in the reverse of the standard direction
so that the rising edge of the signal B leads the rising edge of the signal A.
Refer to the specific “User’s guide”.
On the contrary the correct installation of both the sensor and the tape is mandatory in
an absolute encoder: the absolute measuring system cannot work if it is not mounted as
indicated in the technical documentation.
An arrow printed on the upper surface of the absolute tape is intended to help direct the
sensing head properly in accordance with the mounting instructions: please always check
the cable outlet as well as the direction of the arrow printed on the tape.
In an absolute system the arrow further indicates the standard counting direction.
The standard counting direction means that the count increases when the sensor moves
as indicated by the arrow (provided that the sensor is mounted properly). Please always note
down the direction of the arrow on the tape before applying the cover strip!
For further information on the standard counting direction please refer to the section “A
and B channels (bi-directional output, single ended output)” on page 24 (incremental
encoders) and to the section “Counting direction input” on page 41 (absolute encoders).
To guarantee the encoder reliability over time and a proper working, the operating temperature
range indicated under the section “Environmental specifications” in the datasheet has
to be fulfilled carefully. When operating, the encoder can reach the range of temperature
indicated in the datasheet. Within the stated range of temperature the encoder meets the
performance specifications listed in the datasheet.
The minimum and maximum temperature values have been measured in compliance with
the standards CEI IEC 68-2-1 and CEI IEC 68-2-2.
