Introduction
1.5 Using Advanced Debugging Features
To debug a program or view the I/O, open the Diagnostic panel by clicking on the [Tools] in the Parmeter (Node) Tree
list then click on the [Parameter & I/O View] button. The Diagnostic panel will open. This panel allows the programmer
to monitor and set variables, and to view status of drive digital inputs and outputs.
V Use the up [T] button to move the blue highlighted bar up through the variable list and select a
parameter
Add
Use the [Add] button to open the Parameters dialog box. Select the variable(s) to add by clicking on
the box adjacent to the variable #. When finished selecting variables, click [Add] in the Parameter
dialog box to add these variables to the watch window.
>>
Use the right arrow button to remove highlighted variable from the watch window.
V
Use the down [V] button to move the blue highlighted bar down through the variable list and select
a parameter
Clear
Use the [Clear] button to clear all the parameters listed in the watch window.
Load
Use the [Load] button to load a set of previously saved variables to the watch window.
Save
Use the [Save] button to save the configuration of variables listed in the watch window to a file on
the PC. Configuration can then easily be restored using the [Load] button.

NOTE
Write-only variables cannot be read. Attempts to either display a write-only variable in the diagnostic panel 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 have no
effect. If an analog output is set to “Not assigned” then it can be controlled by writing to the AOUT variable
.
