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
AMM8A absolute modular encoder with SSI and BiSS C-
mode interface
.
This encoder is able to provide a total amount of position information up to 33 bits (21 x 11 bits =
2,097,152 cpr, 4,096 revolutions). Thus the overall length of the SSI data packet is up to 33 bits; while the
overall length of the BiSS data packet is up to 41 bits (33 bit position infor 1 bit error nE + 1 bit
warning nW + 6 bit CRC cyclic redundancy check). It further provides additional 1Vpp sine-cosine signals
for speed feedback (1024 sinusoidal waves per mechanical revolution). For information on the encoder
resolution please see the order code.
To achieve proper installation and correct operation of the encoder a software is expressly developed and
released by Lika Electronic. It allows the operator to set up and calibrate the AMM8A modular encoder
during installation. The program is supplied for free and can be installed in any PC fitted with a Windows
operating system (Windows XP or later).
The name of the program executable file is:
•
IF90-SC_AMM8_BiSS
_vx.x.x.exe for
BiSS interface
encoders;
•
IF90-SC_AMM8_SSI
_vx.x.x.exe for
SSI interface
encoders.
The connection between the encoder and the PC is established by using the kit (IF90-SC USB
cable + AC-DC power supply, order code IF90-SC) expressly supplied by Lika Electronic. The EC-FCI-LK-
TF12-0,5 and EXC-D15M-S71-A16-1,0-FCI-S71 cables must be ordered separately as well as the PF5013
mechanical spacer and the PF5015 positioning tool for mechanical installation.
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
Calibration and synchronization procedure
, specific information on
properly calibrating the encoder during installation is given. In this section the software tool features are
fully described.
In the third section, entitled
SSI interface
, both general and specific information is given on the SSI
interface.
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.
