Pulse output
FMP
(CM Com) Frequency monitor
(pulse output) Outputs a pulse frequency indicating the same as that of the
analog FMA signal.
Transistor
output
Y1 Transistor output1 A running signal, frequency equivalence signal, overload
early warning signal, and other signals from the inverter are
output (as a transistor output) to terminals Y1-Y4. For
details, see "Setting the Terminal Functions E20 to E23" in
Section 5.3 Function Explanation

CME
Transistor output
common Common terminal for transistor output signals
This terminal is insolated from terminals [CM] and [11].
Relay outputs
30A,30B,
30C Alarm output for
any fault
If the inverter is stopped by an alarm (protective function),
the relay (SPDT) will activate.
Contact rating: 250 VAC, .03A - 48V DC, 0.5A
The activation mode can be selected for normal or alarm
operation.
Y5A,Y5C
Multipurpose-signal
relay output
The activation signals can be the same as the Y1 -Y4
outputs above.
The contact ratings are the same as that of the alarm output
above.
Communication
DX+, DX-
RS485
Modbus RTU
communication
Terminals for RS485 communication (Modbus RTU). UP to
31 inverters can be connected using the daisy chain method.
SD
Communication-
cable shield
connection terminal
Terminal for connecting the shield of the communication
cable. The terminal is electrically floating.
(1) Analog input terminals (13,12,V2,C1,and 11)
a. These terminals receive analog signals that may be affected by external noise. The cables should be as short
as possible (66ft /20m or less), be shielded twisted cable, and must be properly grounded. If the cables are
affected by externally induced noise, the shielding effect may be improved by connecting the shield to terminal
[11]. (see Fig. 2-3-8)
b. If contacts are used to connect to these circuits, twin (bifurcated type) contacts for handling low level
signals must be used. A contact must not be connected to terminal [11].
c. If an external analog signal output device is connected to these terminals, it may malfunction as a
result of inverter noise. To prevent malfunction, connect a ferrite core or capacitor to the external analog
signal output device as shown in Fig. 2-3-9.
