1 General
This manual describes commissioning and configuration of the absolute rotary
encoder with PROFIBUS DP interface. The device satisfies requirements for a
PROFIBUS slave according to the PROFIBUS standard and is certified by the
PROFIBUS user organisation.
1.1 Declaration of conformity
Absolute rotary encoders of Series P**58
are developed and manufactured taking
into consideration applicable European standards and directives.
The manufacturer of the product, Pepperl+Fuchs GmbH in D-68301 Mannheim, has
a certified quality assurance program in accordane with ISO 9001.
1.2 Working principle
The basic principle of recording absolute measurement values is optical sensing of a
transparent disk with a printed code that is connected to the shaft to be measured.
The position of the shaft can be determined by evaluating the code at a resolution of
up to 65,536 increments or "steps" per revolution (16 bits).
In the case of Multiturn devices, additional code disks can be included in the circuit
with ratio reduction gears, which can be used to determine the absolute rotation
speed of the shaft (up to 16,384 revolutions = 14 bits).
In the case of an absolute rotary encoder with a PROFIBUS interface, the optically
recorded position value is calculated in an integrated microprocessor and is
transferred with the PROFIBUS.
A corresponding declaration of conformity may be requested from the
manufacturer.
