ACM1
Current output
terminals
(1)
The current
proportional to
output frequency of
the inverter passes
through between I+,
ACM1 or ACM2
terminals. (4-20mA)
(2)
The current output
coefficient is
adjustable between
0-20 through F1515.
Current output range:
4-20mA
Load resistance:
500Ω or less (1) Adjust F1515 so that the
current output under
maximum output frequency
is 20mA or below.
(2) Please select load resistance of
500Ω or below.

TX1+
TX1-
RS485 inverter
signal sending
terminals The terminals are used for
sending
communication
signals by inverter.
•
TX1+ and TX2+ are
terminals with the
same function, and so
are TX1- and TX2-.
When
communicating with
several
inverters,
they can be used as
other connection
terminals of a
inverter.
Communication speed
for RS485 full-duplex
communication mode:
1200-57600bps
Total length: 500m
※
If switch SW2 is
connected, then the
terminating resistor
100Ω will be
connected.
(1) TX1+ is interconnected with
TX2+ internally.
(2) TX1- is interconnected with
TX2- internally.

RX1+
RX1-
RS485 inverter
signal receiving
terminals The terminals are used for
receiving communication
signals by inverter.
•
RX1+ and RX2+ are
terminals with the
same function, and so
are RX1- and RX2-.
When
communicating with
several inverters,
they can be used as
other connection
terminals of a
inverter.
(1) RX1+ is interconnected with

SG RS485
communication
common
terminal This is a RS485
communication common
terminal.
Connected to SG terminal
of each communication
device.
There is a terminal in each of TX

FC1
(1)
These contact output
terminals
indicate
that the protective
function has stopped
the inverter.
(2)
F1513:
multifunctional
contact
outputs
according to the
relay 1 contact
output setting.
Contact capacity
AC250V/0.3A
Alarm contact setting:
:
FA1,2-FC1,2 open
Abnormal:
FA1,2-FC1,2 closed
JP1 Upgrade
jumper Do not connect anything to this terminal except when upgrading.
