4.5 Connecting Terminal Resistors
Connect a terminal resistor to both the communication equipment of the FX PLC and the RDA-RDB signal
terminal in the last inverter.
1. Terminal resistor types
Prepare the following two types of terminal resistors.
Among the terminal resistors supplied with the communication equipment,
select ones with the color codes shown to the right.
1) On the FX PLC side, use a terminal resistor of 110 Ω, 1/2 W supplied
together with the communication equipment operating in accordance with
RS-485.
2) On the inverter side (PU connector except FR-A5NR), use a terminal
resistor of 100 Ω, 1/2 W (not supplied).
3) On the inverter side (FR-A5NR), use a terminal resistor chip (supplied
together with the FR-A5NR).
