2.2.4 Connection to the PU connector
(1) When connecting the control panel or parameter unit using a cable
Use the option FR-CB2
#
or the following connector and commercially available cable:
<Connection 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.
<When using the control panel>
Note:
The rear cover and junction adaptor are required since the circuit board is
exposed in the back of the control panel.
Use the FR-E5P option (cover and adaptor available as a set).
<Maximum wiring length>
!
Control panel (FR-PA02-
02
): 20m
!
Parameter unit (FR-PU04): 20m
(2) For RS-485 communication
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.

1) SG
2) P5S
3) RDA
4) SDB
5) SDA
6) RDB
7) SG
8) P5S
Note: 1. Do not connect the PU connector to a 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 control panel or parameter unit.
Do not use these pins for RS-485 communication.
3. Refer to page 117 for the communication parameters.
