Number of revolutions:
If it is not possible to enter parameter data in the permitted ranges of numerator and
denominator, the attempt must be made to reduce these accordingly. If this is not
possible, it may only be possible to represent the decimal number affected
approximately. The resulting minor inaccuracy accumulates for real round axis
applications (infinite applications with motion in one direction).
A solution is e.g. to perform adjustment after each revolution or to adapt the
mechanics or gearbox accordingly.
The parameter "Steps per revolution" may also be a rational number, however the
"Total measuring range" may not. The result of the above formula must be rounded
up or down. The resulting error is distributed over the total number of revolutions
programmed and is therefore negligible.
Preferably for linear axes (forward and backward motions):
The parameter "Revolutions denominator" can be programmed as a fixed value of
"1". The parameter "Revolutions numerator" is programmed slightly higher than the
required number of revolutions. This ensures that the measuring system does not
generate a jump in the actual value (zero transition) if the distance travelled is
exceeded. To simplify matters the complete revolution range of the measuring system
can also be programmed.
