. Practical example of calculation of parameter “C”.
5.4 Automatic calibration of parameter "C" (recommended)
Start the self-calibration procedure as follows:
press the
+
-
keys simultaneously. The
letter "C" on the display will become fixed and
the number indicated will become <0>,
travel exactly 100m with the machine
– the
pulses will be counted on the display
(1..2..3..)
– and confirm the acquired data by
pressing the
P
SET/RESET
ROGRAMMING
key.
If the acquired value will be less than 30, the
computer will indicate "Err" for about 2 seconds
and then suggest the previously programmed
value.
!
NOTE:
it is recommended to perform the operation at least 2 times in a row,
checking that the detected value is always the same
1 pulse. If the
difference is greater, it means that the speed inductive sensor is NOT
positioned correctly, therefore, you will have to implement the correct
positioning (Figure 4 page 10)
