Preliminary information
This guide is designed to provide the most complete and exhaustive information the operator needs to
correctly and safely install and operate the
SMA1 series absolute linear encoder
. SMA1 is designed to
measure displacements in industrial machines and automation systems. The measurement system
includes a magnetic tape and a magnetic sensor with conversion electronics. The scale is magnetized
with a coded sequence of North-South poles generating an absolute pattern. As the encoder moves
along the magnetic scale, the sensor detects the displacement and yields the absolute position
information through the SSI interface (order code SMA1-GA2-...) or the BiSS B-mode interface (order
code SMA1-SBx-...) or the BiSS C-mode interface (order code SMA1-SCx-...). All versions further provide
additional 1Vpp sine-cosine signals for speed feedback.
It is mandatory to pair the sensor with the
MTA1 type magnetic tape
.
To make it easier to read and understand the text, this guide can be divided into five main sections.
In the first section some general information concerning the safety, the mechanical installation and the
electrical connection as well as tips for setting up and running properly and efficiently the unit are
provided.
In the second section, entitled
SSI interface
, both general and specific information is given on the SSI
interface.
In the third section, entitled
BiSS B-mode interface
, both general and specific information is given on
the BiSS B-mode interface. In this section the parameters implemented in the unit are fully described.
In the fourth section, entitled
BiSS C-mode interface
, both general and specific information is given on
the BiSS C-mode interface. In this section the parameters implemented in the unit are fully described.
Finally, in the fifth section, entitled
1Vpp sine-cosine output signals
, some information is given on the
additional sinusoidal signals.
