6.1 Step-by-step Troubleshooting

After copying the station address from the VLT
®
the VLT AutomationDrive FC 302, power must be cycled
to the FC 302. The master/PLC should now recognise FC
®
302 as a VLT 5000. The NS LED on the MCA 114 option
should now be solid green indicating that communication
between master and slave is established.
If the NS LED flashes, the master/PLC has not recognized
the FC 302:
•
Check if station address is the same in the FC 302
®
as the replaced VLT
•
Check 9-63 Actual Baud Rate. If the frequency
converter has a connection to the master, this
parameter displays the detected baudrate. If no
master has been detected, the parameter
displays: "No baud rate found".
•
Check 9-53 Profibus Warning Word.
