value
must be updated according to the new resolution. A new preset operation
is also required.
NOTE
Any multiturn encoder can be configured so that it works exactly as a singleturn
encoder. This is achieved by setting
6002-00 Programmable total measuring
range = 6001-00 Programmable pulse per revolution (furthermore the
2200-05 Physical Multiturn Resolution [bits] has to be set to 0). Let's
suppose the encoder is set as follows:
6001-00 Programmable pulse per revolution
= 8,192
6002-00 Programmable total measuring range
= 8,192
So it follows that:
Number of revolutions
=
8192 (
6002-00 Programmable total
measuring range )
= 1
8192 (
6001-00 Programmable pulse per
revolution
)
This is exactly the configuration of the singleturn encoder.
Of course the contrary is not possible.
NOTE
Refer to the “7 - Setting-up” section on page 81 for an example of setting the
6002-00 Programmable total measuring range
object.
6003-00 Preset value
[Unsigned32, rw]
This object allows to set the encoder position to a Preset value. The Preset
function is meant to assign a desired value to a physical position of the encoder
shaft. The chosen position will get the value set next to this object and all the
previous and the following positions will get a value according to it. This
function is useful, for example, when the zero position of the encoder and the
zero position of the axis need to match. The preset value will be set for the
position of the encoder in the moment when the preset value is sent. We
suggest setting the preset value when the encoder is in stop.
Default = 0000 0000h
EXAMPLE
Let's take a look at the following example to better understand the preset
function and the meaning and use of the related objects and commands:
6003-
00 Preset value
and
6509-00 Offset value
