Symbol
[FM1] These terminals output monitor signals for analog DC voltage (0 to
[FM2] +10 V) or analog DC current (4 to 20 mA/0 to 20 mA).
[11] Common terminal for analog output signals.
[Y1] Both the SINK and SOURCE modes are supported.
to
(1) Various signals such as "Inverter running," "Frequency arrival
[Y4]
signal," and "Motor overload early warning" can be assigned to
terminals [Y1] to [Y4] by setting function code E20 to E23.
(2) The logic value (1/0) for ON/OFF of the terminals between one
of [Y1] to [Y4] and [CMY] can be switched. If the logic value for
ON between one of [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.
[CMY] Common terminal for transistor output signals
[Y5A/C] (1) Any one of output signals that can be assigned to terminals
[Y1] to [Y4] can also be assigned to this relay contact, as a
general-purpose relay output.
(2) Whether excitation or non-excitation causes this terminal to
output an alarm can be switched.
[30A/B/C] (1) When the protective function is activated, this terminal outputs
a contact signal (1C) to stop the motor.
(2) Any one of output signals that can be assigned to terminals
[Y1] to [Y4] can also be assigned to this relay contact as a
multipurpose relay output, to use it for signal output.
(3) Whether excitation or non-excitation causes this terminal to
output an alarm can be switched.
[DX+]/ These I/O terminals are used as a communications port that
[DX-]/ transmits data through the RS-485 multipoint protocol between the
[SD] inverter and a computer or other equipment such as a PLC.
RJ-45 Used to connect the keypad to the inverter. The inverter supplies
connector the power to the keypad via the extension cable for remote
operation.
CN10 Used as a USB port connector (mini B) that connects the inverter to
a computer. This connector enables connection with the inverter
support loader.
CN11 Connector for an optional battery.
