Yaskawa AOI - Manual (Page 16)

u Test Run
The AOI can test run the motor to which it is connected and help verify communication to the desired drive prior to creating
any type of logic.
Observing the output bits of the AOI while online with the PLC allows users to view the status of the drive. The corresponding
tag displays green when the bit is high.
Users can also enter values into the AOI to send commands through the function block.
For example, enter a value of “1” in the “RunFwd” section to send a forward run command to the drive, and it will set the
forward run command bit high. The “RunningFwd” output bit then turns green to indicate that the drive is running.

u Troubleshooting
The AOI block can help troubleshoot communications between the PLC and drive.
The AOI block will display the status of the AOI tags being used. The block displays the command being issued to the drive
and the drive status information being received from the drive.
