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 multi turn 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.
