Introduction
1.5 Using Advanced Debugging Features
To debug a program or view the I/O, open the Diagnostic window by clicking on the [Tools] in the Parmeter (Node)
Tree list then click on the [Parameter & I/O View] button. The Diagnostic window will open. This window allows the
programmer to monitor and set variables, and to view status of drive digital inputs and outputs.
Click on a variable in the variable list on the right-hand side to select that parameter
< -
Use the left arrow button to add variables after selecting a variable.
- >
Use the right arrow button to remove variables after selecting a variable.
= >
Use the double right arrow button to remove all variables in left-hand Diagnostic window.
R
Use the [ R] (Refresh) button to refresh variable values.

NOTE
Write-only variables cannot be read. Attempts to either display a write-only variable in the diagnostic
window or to read a write-only variable via network communications can show erroneous data.
1.6 Inputs and Outputs
Analog Input and Output
-
The PositionServo has two analog inputs. These analog inputs are utilized by the drive as System Variables and
are labeled “
AIN1” and “AIN2”. Their values can be directly read by the User Program or via a Host Interface.
Their value can range from -10 to +10 and correlates to ±10 volts analog input.
- The PositionServo has one analog output. This analog output is utilized by the drive as a System Variable and
is labeled “
AOUT”. It can be directly written by the User Program or via a Host Interface. Its value can range
from -10 to +10 which correlates to ± 10 volts analog input.
NOTE
If an analog output is assigned to any special function from MotionView, writing to AOUT from the
User Program will not change its value. If an analog output is set to “Not assigned” then it can be
controlled by writing to the AOUT variable.
