8.4.1.2.2 Scaling parameters

The physical resolution of the measuring system can be changed using the scaling parameters. The
measuring system supports the gear function for round axes.
This means that the Number of steps per revolution and the quotient of Revolutions numerator
/ Revolutions denominator can be a decimal number.
The position value output is calculated with a zero point correction, the counting direction set and the
gearbox parameter entered.
MEASURING RANGE
Defines the Total number of steps of the measuring system, before the measuring system starts at 0
again.
Lower limit 16 steps
Upper limit 4 294 967 295 steps (32 bits)
Default 16 777 216
The actual upper limit value to be entered for the Measuring range in steps depends on the
measuring system design and can be calculated using the formula below. As the value "0" is already
counted as a step, the end value = Measuring range in steps - 1.
Measuring range = Steps per revolution * Number of revolutions
For the purposes of calculation the parameters Steps/revolution and Number of revolutions can be
taken from the measuring system type plate.

Risk of physical injury and material damage due to shifting of the zero
point when the measuring system is switched on again after positioning
in de-energized state!
If the number of revolutions is not a power of 2 or >4096, the zero point of the
multiturn measuring system may be lost if more than 512 revolutions are
made in de-energized state!
 Make sure that, for a multiturn measuring system, the quotient of
Revolutions numerator/denominator is a power of 2 from the quantity 2
...2 (1, 2, 4...4096).
