Wiring and configuration of PU connector

Using the PU connector enables communication operation from a personal computer, etc.
When the PU connector is connected to a personal, FA, or other computer with a communication cable, a user program can
run and monitor the converter or read and write to parameters.
PU connector pin-outs
Multifunction regeneration
NOTE
• Pins No. 2 and 8 provide power to the operation panel or parameter unit. Do not use these pins for RS-485 communication.
• Do not connect the PU connector to the computer's LAN board, FAX modem socket, or telephone modular connector. The
product could be damaged due to differences in electrical specifications.
