Every time you change the scaled values (see the
required to set a new preset value (see the
object).
6002-00 Total Measuring Range
[Unsigned32, rw]
WARNING
This object is active only if the bit 2
object is set to ”=1”; otherwise it is ignored and the
system uses the physical values (
6501-00 Hardware counts per revolution
6502-00 Hardware number of turns
) to calculate the position
information.
This object sets a custom number of distinguishable steps over the total
measuring range. In other words, this object allows to set the length of the
travel the encoder has to measure expressed in number of distinguishable steps
(number of information). The total resolution of the encoder results from the
product of
Number of
revolutions
.
You are allowed to set whatever integer value less than or equal to the
overall
hardware resolution
(see the encoder identification label). The overall
hardware resolution results from:
6501-00 Hardware counts per revolution
We recommend the
Number of revolutions
to be set to a power of 2.
The set
Number of revolutions
results from the following calculation:
Number of revolutions
=
Setting the
Number of revolutions
to a value which is a power of 2 is meant
to avoid problems when using the device in endless operations requiring the
physical zero to be overstepped. If you set the
Number of revolutions
which is
not a power of 2, a counting error is generated before the physical zero.
Default = 0800 0000h (134 217 728)
WARNING
When you set a new value next to the
object, please always check also the
value and be sure that the resulting number of revolutions complies with the
Hardware number of revolutions of the device (16,384 revolutions).
Let's suppose that the encoder is programmed as follows:
