Connection To The Pu Connector - Mitsubishi FR-F500 Instruction Manual

2.2.4 Connection to the PU connector

(1) When connecting the operation panel or parameter unit using a connection cable
<Recommended cable connector>
Parameter unit connection cable (FR-CB2) (option) or the following connector and cable.
Connector: RJ45 connector
Example: 5-554720-3, Tyco Electronics Corporation
Cable: Cable conforming to EIA568 (e.g. 10BASE-T cable)
Example: SGLPEV 0.5mm×4P (Twisted pair cable, 4 pairs), MITSUBISHI CABLE INDUSTRIES, LTD.
Note: The maximum wiring length is 20m (65.62feet).
( 2 ) For RS-485 communication
With the operation panel disconnected, the PU connector can be used for 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 allows the inverter to be run and monitored and the parameter values to be read and written.

Note: 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 2) and 8) (P5S) provide power to the operation unit or parameter unit. Do not use these pins
for RS-485 communication.
