Functionality in the PROFIBUS DPV2 device

The velocity calculations are made with a maximum of 19 bits
resolution. If the resolution is higher than 2 19 , the value used for
velocity calculations is automatically reduced to 2 19 .
Example: For an encoder gateway used with a 37 bit multi turn
encoder with a 2 25 single turn resolution and a 2 12
multi turn resolution, the maximum single turn value
for velocity calculations will be 2 19 . For a single turn
encoder the maximum resolution can be up to 31 bit,
but the value used for velocity calculations will in this
case also be 2 19 .
Note: In case of the step/s unit, an average is made over
200ms and the value is multiplied by 5.
Note If scaling has been set on the device the velocity
calculation is based on the scaled position value.
Consequently the accuracy of the velocity value is
dependent of the scaling set to the device.
Note: The velocity function is only supported when using the
encoder gateway and DPV1 functionality.
8.11 Encoder profile version
The encoder Profile Version is the version of the encoder profile
document implemented in the encoder. This parameter is not
affected by the Compatibility mode settings.
