5.1.3 Desired Measuring units reference
With this parameter the reference for the
desired measuring units (cp. 5.1.2) is
determined, either
- per revolution
- per maximum total resolution
- per number of physical impulses
Desired measuring units per revolution
In this case the position value increases by the
programmed number of steps (desired
measuring units) over one revolution.
Additionally the parameter “total resolution” is
used to achieve an adaptation of the
measuring range (cp. 4.1.6).
Desired measuring units per
maximum total
measuring range
The parameter „desired measuring units“ refers
to the complete measuring range of the
encoder, i.e. the encoder gives out the
programmed number of measuring units over
the whole measuring range (4096 revolutions
with the multiturn encoder).
Desired measuring units per
physical impulses
The desired measuring units refer to the
physical impulses entered in octets 35-39
(cp.5.1.7). Physical impulses means: The real
value that is read internally from the code disc
(e.g. 4096 steps per revolution with a standard
12-bit-encoder).
With that option it is possible to set gearing
factors freely.
