Demonstrating Automatic Device Configuration
In this section, you will generate a configuration mismatch by changing a parameter on the drive and then reconnecting it. This
will cause the ADC feature to activate and restore the drive to its programmed configuration.
1. Wait for the drive to be configured from the previous download. That will be indicated in Logix Designer by
the following transition:
2. Unplug one of the Ethernet cables between the controller and the drive. This will generate a fault on the
drive.
3. Press the Stop button to clear the fault from the drive.
4. Using the lessons from the first exercise, change parameter “P033 – Motor OL Current” to 5.0 (or another
value if you desire).
5. Reconnect the Ethernet cable to the drive. This will reinitiate communication between the drive and the
controller, which starts with verifying the configuration signature.
Notice that the PowerFlex 525 drive will get a F048 – Parameters Defaulted fault on the LCD Keypad display after a few
seconds. This is normal and the first step of the Automatic Device Configuration process. The drive is now being
configured.
6. Go back to the I/O Configuration tree in Logix Designer; you will notice a Yellow triangle next to the
PowerFlex 525 drive (PF525_Drive). Click once on the drive to highlight/select it. You will notice that the
drive’s connection status is in a “Configuring” state.
