To calculate, the parameters
steps/rev.
and
the number of revolutions
can be read
on the measuring system nameplate.
The Parameter „Number of revolutions“, which results out of the „total measuring
range in steps“ and „measuring steps per revolution“ has following restriction:
The "number of revolutions" may be a decimal number which can be represented as
fraction in the following area:
1
…256000
= Number of revolutions
1…16384
Example 1:
Assumed
:
-
Measuring range in steps = 16777216
-
Steps per revolution = 2048
Derived:
16777216 steps
= 8192 revolutions =
8192
revolutions => possible
2048 steps/revolution.

Example 2:
Assumed
:
-
Measuring range in steps = 10000000
-
Steps per revolution = 3600
Derived
:
10000000 steps
=

,
2777
revolutions =
25000
revolutions => possible
3600 steps/revolution.

If the resulting number of revolutions cannot be represented in this area, then the
"Measuring range in steps" is corrected to the next smaller value.
The newly calculated total measuring range can be read from the Object 6002h 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.
