2.14 Communication Parameters (Only for the type having the RS-485 communication function)

You can perform communication operation from the RS-485 connector of the inverter through RS-485.

*When "1" is set in the communication parameter n10 "link start mode selection", the inverter is placed in the computer link operation mode at power-on or inverter reset. (Note that it is overridden by the Pr. 79 "operation mode selection" setting.)

REMARKS

Unlike the other inverters, the FR-S500 series is not the type of inverter whose operation panel is removed to make communication.

When the setup software is used to switch to the PU operation mode (Pr. 79 = 1, 3, 4), parameter setting cannot be made. At that time, pressing the RUN key of the operation panel starts the inverter.
