7.4.1.6.2. Parallel - Gray measuring system
If you selected "
PARAL.
" for your special measuring
system in the measuring system input, the following
menu is created:
1.
Enter the resolution of the parallel gray measuring
system.
Here e.g. 500 impulses.
2.
Now declare the input of the lowest-situated bit
(LSB).
In our example the position of the LSB would be at input 7. With a resolution of 500 impulses 9
bits of resolution are needed. The CamCon automatically determines the position of the remaining
inputs once it knows the position of the LSB; they are determined in increasing order. In our
example inputs 7 to 16 would be allocated with the bits of the rotation encoder.
3.
With
Mode
you can choose the encoding of an parallel meassure system by pressing
and
:
you can choose between
Gray
= Gracode and
Bin.
= Binarycode zur Verfügung.
Attention:
Parallel binary encodings shall only be used as an exception. Please implicitly contact
your custoimers service.
4.
Press the
key to confirm your inputs and exit this menu.
7.4.1.6.3. Incremental - measuring system
If you selected "
INC
" for your special measuring system in
the measuring system input, the following menu is
created:
1.
Enter the value of the prescaler (predivisor) with the
and
keys. The prescaler divides or multiplies
the incoming impulses from the measuring system
with the defined value. The following scalers can be
entered: "
*4
", "
*2
", "
*1
", "
/2
", "
/4
", "
/8
", "
/16
", "
/32
",
"
/64
", "
/128
", "
/256
", "
/512
".
Here the prescaler is set to "
*4
". This means that a measuring system with a resolution of 500
impulses supplies the device with 2000 impulses.
2.
Now you enter in the field of the resolution the maximum number of needed impulses. This value
is the maximum resolution, that can be evaluated by the CamCon. If more impulses than this
maximum resolution are counted, the CamCon reports the error message "
Pos Err:3
". In this
case the maximum resolution has to be reset with a higher value or the actual position has to be
set to zero through a clear signal.
3.
In the field "
Clear mode
" you set the functions for the two extra inputs C1 and C2 with the
and
the
key. Here you have the choice between eight possible functions.
"
C1 & C2
"
If input C1 is high and C2 is high, the counter is set to zero.
"
/C1 & C2
"
If input C1 is low and C2 is high, the counter is set to zero.
"
C1 & /C2
"
If input C1 is high and C2 is low, the counter is set to zero.
"
/C1 & /C2
"
If input C1 is low and C2 is low, the counter is set to zero.
"
C1 : W
"
If input C1 is high, the counter is set to zero.
If input C2 is high, the impulses of the measuring system are no longer counted.
"
/C1 : W
"
If input C1 is low, the counter is set to zero.
If input C2 is high, the impulses of the measuring system are no longer counted.
"
C1 : /W
"
If input C1 is high, the counter is set to zero.
If input C2 is low, the impulses of the measuring system are no longer counted.
"
/C1 : /W
".
If input C1 is low, the counter is set to zero.
If input C2 is low, the impulses of the measuring system are no longer counted
(W = Wait).
