* 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
operation panel starts the inverter.
