Communication parameters

2.15 Communication parameters

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 startup 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.

Parameter setting using setup S/W is not enabled in the PU operation mode and external / PU combined operation mode (Pr. 79 = 1, 3, 4). Also, pressing the RUN on the operation panel starts the inverter in the external / PU combined operation mode. (Pr. 79=1, 3)
