Analog Settings (All Models)
Changing Settings Using
Analog Adjustment By adjusting the analog adjuster with a Phillips screwdriver, the value in the
Auxiliary Area can be changed to any value between 0 and 255. This makes it
easy to change set values such as timers and counters without Programming
Devices.
Changing Settings Using
External Analog Setting
Inputs External analog values of 0 to 10 V (resolution: 256) are converted to digital
values and stored in a word in the AR Area. This enables applications that
require on-site adjustment of settings that do not demand a particularly high
degree of accuracy, such as for example, a setting based on changes in out-
door temperatures or potentiometer inputs.

Ladder program
Example: The production quantity could be changed by
changing the counter set value from 100 to 150.
Turning the control on the CP1H changes the
PV in A642 between 0000 and 0255 (00 and
FF hex).
(During the adjustment, the value in A642 is
displayed from 00 to FF on the 7-segment
display.)

Ladder program
Example: The production quantity could be changed by
changing the timer set value from 100 to 150.
When a voltage (0 to 10 V) is input
from a device such as a potentiometer
to the external analog setting input, the
PV in A643 is refreshed between 0000
and 0100 hex (0 to 256).
