Use a screwdriver to turn the adjusting screw of the precision potentiometer (next to
the Arduino Nano) counterclockwise to increase the voltage or to reduce the voltage
clockwise.
Set the voltage to + 10.0 v.
If you have any problems, make sure that the 24V connection is in fact 24V and that
everything has been poled correctly.
Testing the voltage of output 0-10v:
Example of the following preset parameters:
Lower RPM limit (
LR
) = 6000 RPM
Upper RPM limit (
UR
) = 24000 RPM
Turn off the milling spindle.
Berechnung des Drehzahl-Mittelwertes :
Result = (
UR
-
LR
) / 2
RPM =
LR
+ Result.
Result = ( 24000 – 6000 ) / 2 =
9000
RPM = 6000 + 9000 =
15000
Set a speed of 15000 RPM
.
Turn on the milling spindle.
Your meter should now d 5v.
