4.1.3 Start-up
After setting the station address from VLT
®
5000 to VLT
®
AutomationDrive, cycle power on the frequency converter
to activate the new address. The master/PLC now
recognises the frequency converter as VLT
®
5000. A solid
green NS LED on the MCA 194 option indicates that
communication between the master and the frequency
converter is established. If the NS LED flashes, the
master/PLC has not recognised the frequency converter.
