Example - Digital Input
Using Digital Input 4 to select between two Jog speed references of 20.00% and 40.00%:
1. While the drive is stopped, go to Setup|Programming|Inputs|Digital|Digital Input 4 menu.
2. Set Digital Input 4
Destination
to
Jog Reference
(221).
3. Set Digital Input 4
Open Value
to 20.00%.
4. Set Digital Input 4
Closed Value
to 40.00%.
Digital Input 4 will now write the value of 20.00% to
Jog Reference
when the pushbutton is
open. When closed, it will write the value of 40.00%.

7.11 Analog Inputs Block
The Elite Pro has 5 customer configurable analog inputs. Analog
inputs 1-4 can be configured as voltage or current inputs. Analog
input 5 is hardwired as a voltage input. Each input can be configured
to write to any writeable parameter.
Destination (23-27, ICR)
The tag number of the parameter where the analog input
information is to be sent.
Polarity (28-32)
If the input signal is positive only, set to Unipolar. Otherwise,
set to Bipolar for positive and negative inputs.
Filtering (58-62)
An averaging filter can be applied to the incoming signal to
reduce the effects of noise. Increasing the value increases
the filtering.
Type (33-37)
Select either Voltage or Current depending on the type of
input signal. Note that Analog Input 5 is hardwired as a
Voltage input.
Calibrate Analog Input
The Calibrate Analog Input screen provides menu assisted
instructions for setting the 0% Calibration and 100%
Calibration parameters.
0% Calibration (38-42)
This calibration value corresponds to the 12 bit value from
the A2D when the input signal is at zero for bipolar signals,
and the minimum signal for unipolar signals. This defines 0%
input signal. For proper operation, the
0% Calibration
value must be
