Control signal adjustment
DA-088N024PAXXP and DA-088N024PA2XP:
For sequencing and
the electronic limitation of the angle of rotation.
-
Use the Uo potentiometer to set the offset (start point) between 0
to 5 Vdc.
-
Use the
U potentiometer to set the slope (span) between 2 to 30
Vdc.
The Y input is limited to a maximum of 10 Vdc. If the
sum of the offset and slope setting is greater than 10V,
the angle of rotation is reduced providing the feature of
electronic limitation of the angle of rotation.
