2.3.5 Mounting the operation panel (FR-DU07) or parameter unit (FR-PU07)
on the enclosure surface
Having an operation panel or a parameter unit on the enclosure surface is convenient.
With a connection cable, you can mount the operation panel (FR-DU07) or the parameter unit (FR-PU07) to the
enclosure surface, and connect it to the inverter. Use the option FR-CB2
, or the connector and cable available on
the market.
(For mounting the operation panel (FR-DU07), the optional connector (FR-ADP) is required.)
Securely insert one end of connection cable until the stoppers are fixed.
2.3.6 RS-485 terminal block
⋅ Conforming standard: EIA-485(RS-485)
⋅ Transmission format: Multidrop link
⋅ Communication speed: MAX 38400bps
⋅ Overall length: 500m
⋅ Connection cable:Twisted pair cable
(4 pairs)
2.3.7 Communication operation
Using the PU connector or RS-485 terminal, you can
perform 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.
For the Mitsubishi inverter protocol (computer link
operation), communication can be performed with the
PU connector and RS-485 terminal.
For the Modbus-RTU protocol, communication can be
performed with the RS-485 terminal.
For further details, refer to 328.
REMARKS
· Refer to the following when fabricating the cable on the user side. Keep the total cable length within 20m.
