6 Troubleshooting
6.1 Step-by-step Troubleshooting
After copying the station address from the VLT
®
5000 to
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
®
5000.
•
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”.
