3.2 Name of each portion (removing the front cover)
Note1)
Name Description
1) Connector of dedicated operator for
NES1-OP
Dedicated operator for NE-S1 (NES1-OP) can be connected.
2) RUN/STOP/RESET key Push key for run, stop and reset operation.
3) Intelligent relay terminal Output terminal for intelligent relay (1c contact).
4) Main terminal For connecting power supply, motor output and DC reactor.
5) Switch for termination resistor Changeover for integrated resistor (100 Ω ) for RS485.Integrated resistor of 100 Ω is
connected when turning ON.
6) Switch for RS485/OPE Changeover switch for RS422/RS485.
7) RS422/RS485 port Connector for RS485 or external operator and PC software (RJ45 jack)
8) Switch for O/OI (analog input)
changeover Voltage input (O) or current input (OI) can be selected.
9) Logic terminal A,B Terminal for connecting input/output signals (digital/analog) for the inverter control.
10) Charge lamp Turns ON when the internal DC bus voltage is 45V or more.
In case of wiring, maintenance or else, be sure to check that this lamp is turned OFF after
waiting 10 minutes of power OFF.
Note 1) Refer to section 6.5 How To Operate the Inverter.
Note 2) Position of “10) charge lamp” depends on the model. Refer to page 2-11 for the details.
Note 3) Pay attention when operating by PC via “7)RS422/RS485 port”, because the operation can also be done from the
panel of the inverter.
Note 4) Be sure to turn power OFF when connecting or disconnecting the operator such as OPE-SRmini,OPE-S,WOP to the
“7) RS422/RS485 port”.
Note 5) When communication becomes unstable, Please do not use the termination resistor of the inverter. Please use a
termination resistor suitable for your environment.
