Example - Unipolar Analog Input
Setup
Analog Input 3
as a unipolar current input to control the internal
Setpoint C
parameter. Define the 4-20mA current input to produce 0.00%-75.00% speed.
1. While the drive is stopped, go to Setup|Programming|Inputs|Analog|Analog Input 3 menu
section.
2. Set
Analog Input 3 Destination
to
Setpoint C
(236).
3. Set
Analog Input 3 Polarity
to Unipolar.
4. Set
Analog Input 3 Type
to Current.
5. Select Calibrate Analog Input
Step 1. Adjust external current to 4mA. Press ENT when done.
Step 2. Adjust external voltage to 20mA. Press ENT when done.
Step 3. The Elite Pro verifies that the 100% level is greater than the 0% level and
displays the actual levels recorded during the calibration process. Press OK
when done.
6. Set
Analog Input 3 Bias
to 0.00%.
7. Set
Analog Input 3 Gain
to 75.00%.
When any current signal below 4mA is applied, Setpoint C equates to 0.00%. As the current
increases to 20mA, Setpoint C increases to 75.00%.
