2. GENERAL
The AXRES module is targeted for precise absolute rotational angle measurements in harsh
environments such as industrial environment and off road vehicles. Angle sensing is based
on a resolver element. In addition of the rotation angle module measures also the angular
speed and rotational position as whole revolutions. The measurement data is provided to
other devices via CAN open interface which fulfills CIA's (CAN in Automation) device
profile for the encoders (DS406 ver 3.1). Therefore the AXRES can be used as a rugged
replacement for an absolute rotary encoder. AXRES provides 12,5 ... 13.5 bits accuracy per
one electrical revolution. Resolution is sw configurable. The maximum resolution is 22 bits.
Three different form factors allow chosing the most suitable solution for each application.
The newest type AXRES-1X-SL provides very slim desing (diameter 32mm) allowing
resolver to be mounted even inside a hollow pin!
Module is designed to be attached to the application mechanics with two spring type
mounting brackets and an axes adapter. Type of the axis adapter depends on the type of the
housing. For V2 type the internal diameter of the axes adapter is 10mm. Locking to the axes
is secured with three locking screws.
AXRES module is available both in three different type of housings.

Resolved based sensors are not sensitive for vibrations so they provide long service life
without any maintenance even in very harsh environments.
Insensitivity to temperature variations and aging means that the full accuracy is always
achieved.
Product highlights:
•Measures absolute angular rotation (no home point needed), whole rotations and
angular speed
•fullfils CAN open DS301 ver 4.1 communication specification and encoder profile
DS406 ver 3.1
•IP65 protection class for closed type model
•12,5 .. 13,5 bits accuracy per electrical rotation
Applications:
•boom angle measurements (in excavators, lifts etc)
•shaft rotation angle measurements
