7.1.12. RS-485 Bus Connection
One or more frequency converters can be connected to a controller (or
master) using the RS-485 standard interface. Terminal 68 is connected
to the P signal (TX+, RX+), while terminal 69 is connected to the N signal
(TX-,RX-).
If more than one frequency converter is connected to a master, use par-
allel connections.
