1 General
This manual describes installation and
configuration of the Absolute Rotary Encoder
with Profibus DP interface. The device meets
the requirements of a Profibus Slave according
to the PROFIBUS standard. It is certified by the
“Profibus Nutzerorganisation” in Germany.
1.1 Absolute Rotary Encoder
Basic principle of the absolute measurement is
the optical scanning of a transparent disk with
code print. The code disk is connected to the
shaft that is to be measured. By evaluating the
code and two additional incremental signals
the absolute position of the shaft can be
determined with a resolution of up to 8192 steps (13 bits) or 65536 steps per revolution (16
bits).
The absolute shaft position over up to 65536
revolutions (16 bits).
The position value is calculated in an
integrated microprocessor and transmitted
over the Profibus.
1.2 Profibus technology
PROFIBUS is an international, open, non-
proprietary fieldbus standard which is defined
in the international standards IEC 61158. There
are three different versions: Profibus DP,
Profibus-FMS and Profibus-PA. BEI IDEACOD
absolute encoders are designed for the DP
version V0. They support all usual baud rates
up to 12 MBaud.
Besides manufacturer-specific functions, the
devices support the classes 1 and 2 according
to the Profile for Absolute Encoders (this
device profile can be ordered under part
number
3.062 from the “Profibus
Nutzeroganisation”). Further information about
profibus
(functionality, manufacturer,
products), standards and device profiles are
