7.4. Unit configuration (system setting)
Before you are able to use this device, you have to give
it all the information about the parameters of your
measuring system. Select the menu point "
System
setting
" in the main menu. The display shows the
system setting menu:
7.4.1. Measuring system
When you select the menu point "
Measuring system
",
the display changes to the measuring system menu:
Here you can configure the measuring system, the
resolution, the electronic gear, the actual position
hysteresis, the rotation direction and the display format
of the actual position, as well as a special measuring
system. Additionally, the menu point
"Position:"
always shows the actual position of the CamCon. See
also chapter "4.3. The measuring system" on page 20.
7.4.1.1. The standard measuring systems
The display gives the resolution of the measuring
system in steps per rotation. Generally the CamCon
works with a rotation angle coder that has a resolution
of 360 steps per rotation. In this case a change in the
input value is superfluous. Otherwise the CamCon can
be adjusted to the measuring system with the
and
keys. You can choose between the following
predefined resolutions, that are all in accordance with
common rotation encoders: 256, 360, 512, 1000, 1024,
2048, 4096 and 8192 steps. Should you not be able to set values in higher resolution ranges, it is
because there is not enough memory available. If this is the case you have to extend the memory of
the device. Also, you can configure two analog SSI changer modules, AWA/SSI/8 and AWA/SSI/12, for
the gathering of analog signals. These modules are connected to the SSI port of the CamCon.
Note:
Should you not be able to set values in higher resolution ranges, it is because there is not
enough memory available. You will need to upgrade the memory of your device. See also
chapter "12. Calculation the RAM storage-requirement for" on page 84.
7.4.1.2. The actual position hysteresis
At the menu point
"Hyst."
you enter the actual position
hysteresis.
This value is needed to suppress the flashing of the
outputs during uneven data gathering. The exact value
can only be determined through experiments, though it
should be as small as possible or always "0". The
hysteresis can be between 0 and 1/4th of the total
resolution, but can never exceed 255 impulses.
