Standard scaling parameter (≤ 32 bit)
To use “Attribute 16, Measuring Units per Span” and “Attribute 17, Total Measuring
Range in Measuring Units
” the “Attribute 105, TR-Parameter in use (scaling)” must be
set to “0”.
Danger of personal injury and damage to property exists if the measuring
system is restarted after positioning in the de-energized state by shifting
of the zero point!
If the number of revolutions is not an exponent of 2 or is >4096, it can occur, if
more than 512 revolutions are made in the de-energized state, that the zero
point of the multi-turn measuring system is lost!
Ensure that the
