Absolute Rotary Encoders
Data Model for the Device Configuration
6.2.4 Object 6003h: Preset value
This object specifies the preset value for the output position value. You can assign a desired
output value to a rotary encoder position using the preset value.
6.2.5 Object 6004h: Position value
This object contains the process value of the absolute rotary encoder.
r-map (read only MAPable): Parameter can be queried by PDO.
6.2.6 Object 6500h: Operating status
This object provides information on the operating status of the absolute rotary encoder. It
contains information about internally programmed parameters.
Note!
The ESI file contains a default value of 1000h for the object. You must adapt this value to the
specific rotary encoder value using the project tool.
To do so, observe the information on the nameplate of the rotary encoder and the type code in
the corresponding datasheet. Use object 1010h to save the parameters in the non-volatile
memory.
Note!
Important application note
Dividing the "Total resolution" (as a decimal number) by "Measuring steps per revolution" must
result in an integer.
The total resolution must also fit into an integer multiple of 4096 for a rotary encoder with 12 bits
per revolution. This means that 100 or 325 revolutions, for example, could result in faults.
Therefore, the following equation must be observed:
(4096 x measuring steps per revolution)/total resolution = integer value
Subindex Description Data type Default Access
0h Preset value Unsigned 32 - r/w
Note!
After setting the preset value, you must still store this in the non-volatile memory via object
1010h, otherwise it will no longer be present after the rotary encoder is turned off.

0h Process value Unsigned 32 r-map
