Pr. 342 "E PROM write selection"
Used to perform required settings for RS-485 communication between the inverter and
personal computer.
POINT
<To perform computer link operation>
! Set "100, 101, 110 or 111" in Pr. 119 to make NET mode communication.
! Presetting any value other than "0" in Pr. 122 enables communication between the
computer and inverter.
! When the communication option is fitted, NET mode communication cannot be
used if "100, 101, 110 or 111" is set in Pr. 119.
! When "1" is set in Pr. 340, 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.)
! Refer to page 13 for wiring.
