You can create a network of drives by linking a Master (PC/PLC) to one or more 650V drives
fitted with this additional 3-way terminal. It is factory-fitted to the right hand side of the control
board.
Signals from the host 650V drive are converted into RS485, and vice versa, so that information
can be shared between the Master and 650V drive(s).
Wiring is very simple - all connections are SELV (Safe Extra Low Voltage).

Terminators
The last drive in a system must have a terminating resistance. All other drives in the system
should not have a terminator.
Frames 1-3 drives require a 120
Ω
terminating resistor
fitting to terminals 17 and 18 on the Control Board
(resistor is
±
1%, minimum ¼ Watt).
Frames C-F drives are fitted with an integral resistor,
switched in and out by switch SW1 on the Control
Board.
IMPORTANT:
Failing to use a terminating resistance may result in
unreliable operation.
