Symbol Name Functions
[EN1] Enable input 1
[EN2] Enable input 2
(1) Opening terminals [EN1] and [PLC] or terminals [EN2] and [PLC]
stops the inverter's output transistor.
(2) These terminals are exclusively used for the SOURCE mode input and
cannot be switched to the SINK mode input.
(3) If input to either one of [EN1] and [EN2] is OFF, the inverter issues an
alarm (ECF).
[PLC] Power for
programmable
logic controller
signals Connects to PLC output signal power supply.
Digital input
[CM] Digital input
common Two common terminals for digital input signals.
[FM1]
[FM2]
Analog monitor These terminals output monitor signals of analog DC voltage (0 to +10 V)
or analog DC current (+4 to +20 mA DC or 0 to +20 mA DC).
Analog output
[11] Analog common Two common terminals for analog input and output signals.
[Y1] Transistor
output 1
[Y2] Transistor
output 2
[Y3] Transistor
output 3
[Y4] Transistor
output 4
Both the SINK and SOURCE modes are supported.
(1) Various signals such as inverter running, frequency arrival and
overload early warning can be assigned to terminals [Y1] to [Y4] by
setting function code E20 to E23.
(2) It is possible to switch the logic value (1/0) for ON/OFF of the
terminals between [Y1] to [Y4], and [CMY]. If the logic value for ON
between [Y1] to [Y4] and [CMY] is 1 in the normal logic system, for
example, OFF is 1 in the negative logic system and vice versa.

[Y5A/C] General-purpose
relay output
(1) A general-purpose relay contact output usable as well as the function
of the transistor output terminal [Y1], [Y2], [Y3] or [Y4].
(2) Whether excitation or non-excitation causes this terminal to output an
alarm can be switched.
Relay
output
[30A/B/C] Alarm relay output (1) Outputs a contact signal (1C) when the protective function has been
activated to stop the motor.
(2) Any one of output signals assigned to terminals [Y1] to [Y4] can also
be assigned to this relay contact to use it for signal output.
(3) Whether excitation or non-excitation causes this terminal to output an
alarm can be switched.
DX+/DX-
/SD RS-485
communications
port 2
(Terminal block) The communications port transmits data through the RS-485 multipoint
protocol between the inverter and a computer or other equipment such as a
PLC (Programmable Logic Controller).

communications
port 1
(Standard RJ-45
connector) Used to connect the inverter with the keypad. The inverter supplies the
power to the keypad through the pins specified below. The extension cable
for remote operation also uses wires connected to these pins for supplying
the keypad power.
