ital inputs:
Automatic mode (AUT)
In AUT mode the variable speed drive works with PID control, where the PID setpoint is set from ke
y
pad and the feedback is monitored from the AI1 analog input.
In this example we have assumed that on the AI1 analog input is connected a pressure sensor with output 0-10V, correspondent to a pressure of 0-15Bar with a linear characteristic, as shown in the followin
g
d
iagram.
This means that: if the output of the sensor is 0V it means a pressure of 0 Bar, if the output of the sensor is 10V it means a pressure of 15 Bar, if the output of the sensor is 5V it means a pressure of 7.5 Bar, and so

Manual mode
(

In MAN mode the PID control is de-activated and the variable speed drive works with manual regulation o

Example of use.
Once the parameters listed above have been set on the VLA1, test the functionin
g
:
–
Keep opened the DI2 digital input to allow the enable of the automatic mode (AUT).
–
With the buttons of the keypad set a PID setpoint, which for this specific example it corresponds to a pressure setpoint. For example, set a PID setpoint of 4.0 PID Unit (= 4 Bar).
–
The VLA1 read the value of the pressure of the plant
(
PID feedback
)
from the AI1 analog input, to which is connected the output of a pressure sensor. The 0- 10V voltage signal of the pressure sensor i
s
automatically transformed by the VLA1 in a pressure value according to the parameters previously set
(
in this example: 0V = 0 Bar, 10V = 15 Bar
)
.
–
Close the DI1 di
g
ital input to run the motor
.
–
If the pressure of the plant is lower than the setpoint
(
e.g. 2 Bar, which is lower than 4 Bar
)
the VLA1 increases the speed of the motor by regulating the output frequency until the PID setpoint is reached. In this
specific example, the output frequency of the drive when PID control is active is limited to the 20% and 80% of the maximum frequency
(
50Hz
)
, which means from 10Hz to 40Hz.
–
If you want to switch the operating mode to manual mode (MAN) close the DI2 digital input.
–
Now the PID control is de-activated
(
the value of AI1 signal is ignored
)
. The output frequency of the drive is adjusted with the external potentiometer, connected to the AI2 analog input. In this specific example, the
output frequenc
y
regulated with the potentiometer can be ad
j
usted from 0Hz to 50Hz.
–
To command the motor stop, open the DI1 digital input
.
