"Steps per revolution"
-
"Total measuring range"
If Class 2 is switched off, the position value cannot be scaled or adjusted.
6.9.7 Scaling parameter PNO CLASS 2
If the scaling parameters are activated with the
Scaling function
, the physical
resolution of the measuring system can be changed. The position value output is
binary decoded and is calculated with a zero point correction and the count direction
set. The measuring system does not support decimal numbers in this configuration or
numbers of revolutions (gearbox function) deviating from exponents of 2.
6.9.7.1 Steps per revolution
Defines how many steps the measuring system outputs for one revolution of the
measuring system shaft.
lower limit
1 step / revolution
upper limit
8192 steps per revolution (Max. value see nameplate)
default
4096
6.9.7.2 Total measuring range
Defines the
total number of steps
of the measuring system before the measuring
system restarts at zero.
lower limit
16 steps
upper limit PNO CLASS 2 16 bit
65536 steps
upper limit PNO CLASS 2 32 bit
33554432 steps (25 bit)
default
16777216
The actual upper limit for the measurement length to be entered in steps is dependent
on the measuring system version and can be calculated with the formula below. As
the value "0" is already counted as a step, the end value = measurement length in
steps - 1.
Total measuring range = Steps per revolution * Number of revolutions
To calculate, the parameters
steps/rev.
and
the number of revolutions
can be read
on the measuring system nameplate.
