4.8.5 USB Data Communication
Illustration 4.13 Network Bus List
When the USB cable is disconnected, the frequency
converter connected via the USB port is removed from the
Network bus list.
NOTICE
A USB bus has no address-setting capacity and no bus
name to congure. If connecting more than 1 frequency
converter through USB, the bus name is auto-
incremented in the MCT 10 Set-up Software Network bus
list.
Connecting more than 1 frequency converter through a
USB cable often causes computers installed with
Windows XP to throw an exception and crash. Therefore
it is advised only to connect 1 frequency converter via
USB to the PC.
