5.15.1 Wiring and configuration of PU connector

Using the PU connector as a computer network port enables communication operation from a personal computer, etc.
When the PU connector is connected with a personal, FA, or other computer by a communication cable, a user program can
run and monitor the inverter or read and write to parameters.
