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
SMRA series bearingless absolute encoder
.
SMRA is designed to measure rotary and linear displacements in industrial machines and automation
systems. The measurement system includes a magnetic ring and a magnetic sensor with conversion
electronics. The ring is magnetized with a coded sequence of North-South poles generating an absolute
pattern. As the ring turns without contact, the sensor detects the rotation and yields the absolute
position information through the SSI interface (order code SMRA-BGx-... and SMRA-GGx-...) or the BiSS
C-mode interface (order code SMRA-SCx-...).
It is mandatory to pair the sensor with the specific
MRA type magnetic ring
. See the order code:
SMRA-GG1-...
R1
: R1 = MRA/130-64N ring model.
To make it easier to read and understand the text, this guide can be divided into three 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 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.
