The measuring system uses two input words for the position plus a separate input word
for the velocity, and two output words which are consistently transferred via the bus. The
velocity is output with a sign in revolutions per minute and has an accuracy of +/- 1 rpm.

The configurations designated "TR-mode" are not compatible with the PNO encoder
profile in terms of the parameter record. The scaling function prescribed by the PNO
profile is a simple special case of a general gear. Due to the extended 'gear' scaling
function, additional parameters are therefore necessary in order to describe the gear
fully.
In other words, the TR-specific modes represent an extension of the measuring
system function which is not restricted by its compatibility with the PROFIBUS-DP
and certification.
