Description
This series of PROFIBUS rotary encoders is based
on the modern fast technology of singleturn sampling and the mechanical gear box of the multiturn
unit. The absolute encoder corresponds to the
PROFIBUS profile for encoders, order no. 3.062.
Operation is supported based on Class 1 and Class
2.
For operation based on Class 1, position data and
diagnostic data bytes 1 ... 16 are available. In addi-
tion, the direction of the code can be selected as
either cw ascending (clockwise rotation, code
course ascending) or cw descending (clockwise rotation, code course descending).
If the rotary encoder is operated according to Class
2, additional functions to those from Class 1 are
available. These include scaling of the resolution
per revolution and the overall resolution, as well as
the preset function. In addition, expanded diagnostic reporting is supported.
Besides, the rotary encoder offers extended functionalities such as speed transfer, extended scaling
functions, programmable limit switches and a commissioning mode.
The removable connecting hood contains a slide
switch for setting the terminating resistor and the
rotary switches for setting the address. Assign a
fixed address and bus termination to the encoder
with this switches.
The absolute encoder is mounted directly onto the
application shaft, without any coupling. Rotation of
the absolute encoder is prevented by a torque rest.

Addressing
Adjusting the participant address
The participant address can be adjusted with the rotary switches. The address can be defined between 1 and 99, and may
only be assigned once.
Adjusting the termination resistor
The terminating resistor RT (220 Ω) can be connected to the circuit by means of the switch:

- wrong address adjusted
- wrong bus wiring
