3.4.3 Scaling
The resolution is specified by the curve gradient; the
measuring range is specified by the start point and end
point.
: Start point of the curve with associated output value.
: End point of the curve with associated output value.
R : The present position of the magnet is read
ead position
(teach-in).
To set the values, see also "Setting the curve" in
section 3.4.6.
Setting the resolution
The curve gradient can be changed by fixed increments.
► Set value using the spin controls under Scaling.
Setting the start points and end points
► For the start point and end point, the present position
of the magnet on the BTL is read (teach-in).
Or
► Use the mouse to move the start point and end point in
the graphical display.
Or
► Set values using the spin controls.
Or
► Enter values and confirm each by pressing <Enter>.
You might have to first adjust the limits and error value in
order to set the scaling.
3.4.4 Limits and error value
Setting upper limit, lower limit, and error value
Measuring range/limits: The start and end points must
lie on or within the limits and they must keep a minimum
distance from the error value.
Error value: The error value must lie on or outside the
limits. A minimum distance from the start or end point of
the measuring range must be kept.
The error values "all data bits 1" and "MSB only"
can only be selected if the bit number is ≤ 25.
The error value "compatible with BTL5 (bit 21)"
is only possible if the bit number is ≥ 22.
Setting limits and error value
► Set values using the spin controls.
Or
► Enter values and confirm by pressing <Enter>.
► Select the appropriate error value.

3.4.5 Gray bar
The selected function (see 3.4.1) is shown and the data
format for the SSI interface (see 3.4.2) is displayed
graphically in the gray bar over the output characteristics.
3.4.6

Output characteristics

Graphical representation of the curve as a function of the
scaling.
Offset and gradient are displayed when the
mouse cursor is moved over the start point
or end point .
Setting the curve
► Use the mouse to move the points.
⇒ The curve and associated values will be changed.
► The characteristic curve can be inverted.
Note the following when making this setting:
– For "Position", the distance between the start point
and end point must be at least 4 mm (0.15 inches).
– For "Velocity", the distance between the start point and
end point must be at least 100 mm/s (4 inches/s).
– Identical values may not be selected for the start point
and end point.
– The minimum nominal length of the BTL for the
"Differential position" function is 90 mm.
– For the "Differential position" function, the minimum
distance between two magnets is 65 mm.
– The maximum configurable velocity is 10 m/s.
Values and settings in blue text indicate
changes to the configuration. U
the configuration to the BTL.
Check output
The results of the configuration are displayed online on the
"Magnet" tab.
► Click on U
.
pdate btl
⇒ The configuration is sent to the BTL.
► Switch to "Magnet" tab.
⇒ The set function is displayed.
⇒ The movements of the magnets and the LED
signals are shown online.
Negative values can only be output in binary
format if the bit number is ≤ 25. Negative values
in Gray format are only possible if the bit
number is = 25.
