Using the PU connector for computer link

(1) When connecting the operation panel or parameter unit using a connection cable
Refer to the Instruction Manual (basic).
(2) For RS-485 communication
The PU connector can be used to perform communication operation from a personal computer etc.
By connecting the PU connector to computers such as a personal computer and Factory Automation computer with
a communication cable, you can monitor the inverter operation and read and write parameters using a user
program.

1. Do not connect the PU connector to the computer's LAN board, FAX modem socket or telephone
modular connector. Otherwise, the product may be damaged due to electrical specification
differences.
2. Pins No. 2 and 8 (P5S) provide power to the operation panel or parameter unit.
Do not use these pins for RS-485 communication.

Type
FA-T-RS40
* You can not connect multiple inverters with a converter cable (a computer and an inverter are one-to-one
connection). As the RS-232C cable and the RS-485 cable (10BASE-T+RJ-45 connector) are provided with a
product, no need to prepare a cable and a connector separately. Contact a maker for details of the product.
