When entering parameter data, ensure that the parameters
"Total measuring
range"
and
"Steps per revolution"
are selected such that the quotient of the two
parameters is an exponent of 2.
If this is not the case, the measuring system corrects the measurement length in
steps to the next smallest exponent of 2 revolutions. The Steps per revolution
remains constant.
The newly calculated total measuring range can be read from the extended diagnosis
information for CLASS 2 and is always shorter than the specified measurement
length. It may therefore occur that the total number of steps actually required is not
achieved and the measuring system generates a zero transition before it reaches the
maximum mechanical distance.
As the internal absolute position (before scaling and zero point adjustment) is
periodically repeated after 4096 revolutions - for applications where the number of
revolutions is not an exponent of 2 and rotation is infinitely in the same direction,
there is always an offset.
For such applications, one of the TR configurations
"TR-Mode Position"
or
"TR-Mode Po Velocity"
are always to be used.
