changeover
9) Logic terminal A,B
10) Charge lamp
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.
Dedicated operator for NE-S1 (NES1-OP) can be connected.
Push key for run, stop and reset operation.
Output terminal for intelligent relay (1c contact).
For connecting power supply, motor output and DC reactor.
Changeover for integrated resistor (100Ω) for RS485.Integrated resistor of 100Ω is
connected when turning ON.
Changeover switch for RS422/RS485.
Connector for RS485 or external operator and PC software (RJ45 jack)
Voltage input (O) or current input (OI) can be selected.
Terminal for connecting input/output signals (digital/analog) for the inverter control.
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.
