Use the Interactive Test Panel to test and debug your motion system and configuration settings on the selected axis. With the Interactive Test Panel you can perform a simple straight-line move and monitor feedback position and position error information, move and I/O status information, change move constraints, get information about software errors and faults, and view position or velocity plots of the move.
Complete the following steps to test your setup after configuring the axis using the Axis
Configuration dialog box.
1.
Right-click the axis in the Project Explorer window and select Interactive Test Panel from the shortcut menu. Opening this dialog box sends the axis settings to the hardware and activates the I/O on the module.
2.
On the Move tab set Move Mode to Relative Position and Target Position to 20 rev.

3.
On the Move Constraints tab set Velocity to 2 rev/sec, Acceleration and Deceleration to
20 rev/sec 2 , and Acceleration Jerk and Deceleration Jerk to 200 rev/sec 3 . Using the encoder counts per revolution and stepper steps per revolution values specified in this tutorial the motor will move 20 revolutions at 120 rpm.
Tip
Click the Help button ( ) on the bottom of the dialog box for detailed information about the items available in this dialog box.
4.
Click the Enable button ( ) on the bottom of the dialog box to enable the drive.
5.
Click the Start button ( ) on the bottom of the dialog box to start the move with the configured options.
6.
Use the Status and Plots tabs to monitor the move while it is in progress.
Finalize your motion system setup by connecting and configuring additional I/O such as limits as required by your system using the 37-pin terminal block.
