Typographic and iconographic conventions
In this guide, to make it easier to understand and read the text the ollowing typographic and
iconographic conventions are used:
•parameters and objects both o Lika device and inter ace are coloured in GREEN;
•alarms are coloured in RED;
•states are coloured in FUCSIA.
When scrolling through the text some icons can be ound on the side o the page: they are expressly
designed to highlight the parts o the text which are o great interest and signi icance or the user.
Sometimes they are used to warn against dangers or potential sources o danger arising rom the use o
the device. You are advised to ollow strictly the instructions given in this guide in order to guarantee
the sa ety o the user and ensure the per ormance o the device. In this guide the ollowing symbols are
used:
This icon, ollowed by the word WARNING, is meant to highlight the parts o the
text where in ormation o great signi icance or the user can be ound: user must
pay the greatest attention to them! Instructions must be ollowed strictly in order
to guarantee the sa ety o the user and a correct use o the device. Failure to heed
a warning or comply with instructions could lead to personal injury and/or damage
to the unit or other equipment.
This icon, ollowed by the word NOTE, is meant to highlight the parts o the text
where important notes need ul or a correct and reliable use o the device can be
ound. User must pay attention to them! Failure to comply with instructions could
cause the equipment to be set wrongly: hence a aulty and improper working o
the device could be the consequence.
This icon is meant to highlight the parts o the text where suggestions use ul or
making it easier to set the device and optimize per ormance and reliability can be
ound. Sometimes this symbol is ollowed by the word EXAMPLE when instructions
or setting parameters are accompanied by examples to clari y the explanation.

Preliminary information
This guide is designed to provide the most complete and exhaustive in ormation the operator needs to
correctly and sa ely install and operate the AMM36 absolute kit encoder.
This encoder is available with the ollowing inter aces:
•SSI inter ace;
•BiSS C-mode inter ace;
•RS-485 serial inter ace.
AMM36 encoder can be both singleturn and multiturn.
Singleturn resolution can be 17 bits (131,072 cpr), 21 bits (2,097,152 cpr), and 22 bits (4,194,304 cpr).
In multiturn versions, the number o revolutions is 65,536.
It urther provides additional 1Vpp Sine-Cosine signals or speed eedback (256 sinusoidal signals per
revolution).
AMM36 is ideal or integration into space critical applications such as robots, robotic joints, hollow sha t
motors (direct drive torque motors, …), brushless and servo motors, drones / UAVs, electromedical
devices, OEM equipment.
To make it easier to read and understand the text, this guide can be divided into two main sections.
In the irst section some general in ormation concerning the sa ety, the mechanical installation and the
electrical connection as well as tips or setting up and running properly and e iciently the unit are
provided.
In the second section, entitled SSI interface, both general and speci ic in ormation is given on the SSI
inter ace, see on page 27.
In the third section, entitled BiSS C-mode interface, both general and speci ic in ormation is given on
the BiSS C-mode inter ace. In this section the parameters implemented in the unit are ully described.
See on page 31.
In the ourth section, entitled RS-485 serial interface, both general and speci ic in ormation is given
on the serial inter ace, see on page 41.
WARNING
Light alters signi icantly the proper operation o the system.
Please mount the motor cap and protect the encoder rom light sources be ore starting the
system and checking its operation. The encoder has been calibrated to per orm at its best
without any light inter erence.
WARNING
The encoder must be adequately protected under an enclosure appropriate or the speci ic
application.

AMM36 • SSI, BiSS, & RS-485
1 - Safety summary
1.1 Safety
•Always adhere to the pro essional sa ety and accident prevention regulations
applicable to your country during device installation and operation;
•installation and maintenance operations have to be carried out by quali ied
personnel only, with power supply disconnected and stationary mechanical
parts;
•device must be used only or the purpose appropriate to its design: use or
purposes other than those or which it has been designed could result in
serious personal and/or the environment damage;
•high current, voltage and moving mechanical parts can cause serious or atal
injury;
•warning! Do not use in explosive or lammable areas;
•ailure to comply with these precautions or with speci ic warnings elsewhere
in this manual violates sa ety standards o design, manu acture, and
intended use o the equipment;
•Lika Electronic assumes no liability or the customer's ailure to comply with
these requirements.
1.2 Electrical safety
•Turn o the power supply be ore connecting the device;
•connect according to explanation in the “4 - Electrical connections” section
on page 20;
•in compliance with the 2014/30/EU norm on electromagnetic
compatibility, ollowing precautions must be taken:
- be ore handling and installing, discharge electrical charge rom
your body and tools which may come in touch with the device;
- power supply must be stabilized without noise, install EMC ilters on device
power supply i needed;
- always use shielded cables (twisted pair cables whenever possible);
- avoid cables runs longer than necessary;
- avoid running the signal cable near high voltage power cables;
- mount the device as ar as possible rom any capacitive or inductive noise
source, shield the device rom noise source i needed;
- to guarantee a correct working o the device, avoid using strong magnets on
or near by the unit;
–minimize noise by connecting the shield and/or the rame to ground. Make
sure that ground is not a ected by noise. The connection point to ground
can be situated both on the device side and on user’s side. The best solution
to minimize the inter erence must be carried out by the user.
1.3 Mechanical safety
•Install the device ollowing strictly the in ormation in the “3 - Mounting
instructions” section on page 12;
•mechanical installation has to be carried out with stationary mechanical
parts;

AMM36 • SSI, BiSS, & RS-485
•do not disassemble the encoder;
•do not tool the encoder or the disk/ring;
•delicate electronic equipment: handle with care; do not subject the device
and the disk/ring to knocks or shocks;
•respect the environmental characteristics declared by manu acturer;
•the encoder must be adequately protected under an enclosure appropriate
or the speci ic application.
1.4 Specific handling and cleaning instructions and safety information
against electrostatic discharges
Please be sure to strictly observe the ollowing sa ety precautions and
instructions be ore handling and installing the kit encoder.
•Open the box and handle the electronic components only within an EPA
(Electrostatic Protective Area) and when you are properly grounded;
•be ore handling the kit encoder the operator must wear:
-a wrist strap; it must be worn on the hand and connected to ground
through a 1 megohm resistor;
-an ESD smock made o dissipative material;
-dissipative gloves; they are urther used not to dirty the code disk while
mounting;
•always handle the encoder by grasping the enclosure on the sides;
•the code disk must always be handled by grasping its outer edges or the
magnetic ring;
•avoid lexing the disk, exposing it to direct sunlight, excessive heat and/or
humidity;
•i dust or ingerprints get on to the disk, wipe with a so t dry cloth or camera
lens tissue; wipe the disk using circular motions; more stubborn ingerprints
or stains can be removed using a so t cloth lightly moistened with a ew
drops o alcohol; do not use gasoline, kerosene, benzene or other solvents, as
they damage the disk.
