EXAMPLE
Let's take a look at the following example to better understand the preset
function and the meaning and use of the related attributes:
and
The encoder position which is transmitted results from the following
calculation:
Transmitted value
=
read position
(it does not matter whether the position is
physical or scaled) +
preset setting, then the transmitted value and the read position are necessarily
the same as
= 0 and
= 0.
and then execute the preset setting,
the system saves the current encoder position in the
attribute. It follows that the transmitted value and the
are the same as
read position
current position of the encoder as you wish.
For example, let's assume that the value “50” is set next to the
attribute and you execute the preset setting when the encoder
position is “1000”. In other words, you want to receive the value “50” when the
encoder reaches the position “1000”.
We will obtain the following information sequence:
Transmitted value
=
read position
(=”1000”) = 50.
The following transmitted value will be:
Transmitted value
=
read position
(=”1000”) = 51.
And so on.
