5.2.3 Connecting terminating resistors
Congure and connect a terminating resister to the inverter farthest from the FX5 programmable controller.
FX5 programmable controller side of connections
The built-in RS-485 port, the FX5-485-BD and the FX5-485ADP have internal terminating resistors.
Set the terminating resistor selector switch to 110Ω.
Inverter side of connections
Reections may interfere with communication depending on transmission speed and distance. Connect a
terminating resistor if these reections begin to interfere with communication.
● PU connector
The user must prepare one terminating resistor of 100Ω, 1/2W.
• Connect the terminating resistor between number 3 pin (RDA) and number 6 pin (RDB).
• Use a switch as a terminating resistor cannot be installed to PU connectors.
• Connect the terminating resistor to only the inverter farthest from the programmable controller.
