Target Value

Value shown on the first line of the display which indicates the position which must be reached by manual
adjustment.
Backlash compensation value

If set different to zero, at each inversion of the rotation direction, the displayed value does not change until
the shaft completes a rotation which is equal to or above the backlash compensation value.
Set a positive value for backlash compensation in the forward direction and a negative value for
compensation in the reverse direction.

When the actual value reaches inside the window around the target value (which is defined by the tolerance)
the red LED is turned off the green LED is turned on.
Example: with target value

Adjustment of displayed value
After the installation of instrument on the machine and setting of all parameters, in order to visualize on the
display the correct value it is necessary to carry out the reset or preset.
Position the shaft in a position where the correct measurement that has to be visualized is known exactly (for
example the stroke end point) or measure the position in that position of the shaft. Program parameter
+//
+//
+//
+//
with value 3 in the first digit on the right and exit programming.
Now press
O
and
./
./
./
./
will appear, press again 2 times
O
and set the correct value to display, then confirm
with
O
The display will now show the desired value.
If the required value is zero, instead of the preset function it is possible to use the reset function by setting 1
in the first digit on the right in the
//
//
//
//
parameter so that pressing
O
will bring the displayed value to zero.
Now that the instrument is adjusted, it is necessary to insert the desired
//
//
//
//
parameter to avoid
accidental reset/preset of the displayed value.
