The Profibus-DP interface supports CLASS 1 and CLASS 2 functionality according to the encoder profile. In addition to these functions the GSD-file

supports further features, for example software limit switches. Further more, the following encoder parameters can be programmed directly via the

Profibus-DP network without any extra device.

Counting Direction

This parameter counting direction defines whether the output code increases or decreases when the shaft

rotates clockwise

Resolution (Positions per Turns)

The parameter ‘resolution per revolution’ is used to program the desired number of steps per revolution.

Each value between 1 and the physical resolution per revolution can be programmed

Total Resolution “Max-RANGE“

This parameter is used to program the desired number of measuring units over the total measuring range.

This value may not exceed the total physical resolution of the absolute rotary encoder

Reset (RAX)

The preset value is the desired position value, which should be reached at a certain physical position of the

axis. The position value is set to the desired process value by the parameter preset

Velocity

The implemented software can additionally deliver the current velocity. This value is transmitted in binary

code, 16 Bit, in addition to the process value. It is possible to choose between four different units: steps per

10 ms, per 100 ms, per 1000 ms and revolutions per minute

Software Limit Switches Function

Two software limit switches can be set. If the position value falls below the lower or exceeds the higher

limit switch, a status bit in the process value is set

Teach-In (Online Parameterization)

A special mode is available for commissioning phase of the device. This makes it possible to change

parameters while the encoder is in data exchange mode
