Note 1) It is necessary to set changeover switch and the parameter C070 for releasing the Modbus
communication. If the parameter C070 is set to Modbus, external operator via the RJ45 jack
cannot be used.
Note 2) Connecting work on RJ45 jack must be done during the inverter power off.
- Turns on (red) during inverter is powered up
- Turns on (green) during inverter operation. (This turns ON either Run command
is given, or the inverter is giving out power. Therefore it keeps turning on during
0 Hz driving, or keeps turning on during deceleration period even after the run
command is OFF.
- Turns on (red) when the inverter is in trip status.
- See section 6.8 for details on clearing alarms.
- Turns on (green) when the RUN/STOP/RESET is ready. It turns off when there
is a RUN command. If the run command is being given from the
RUN/STOP/RESET key, the lamp is being on during deceleration period even
after the run command is OFF. While Run command is given such as FW(RV)
terminal,if "RUN/STOP/RESET key" was pressed, even Run command is OFF,
the "Key valid lamp" is OFF until inverter is Stopped.
- Makes inverter run, stop and reset. RUN/STOP/RESET key is set default and it
can be made invalid by the key sensitivity selection (C151) to "no".
- It restores from the trip state if the inverter is in trip state.
- If the ModBus communication is selected, it can be temporary changed to a
external operator mode if the inverter is powered up with pressing the
RUN/STOP/RESET key and keep it pressing 5seconds,and take off from the
key.. Changeover switch must be changed later on. Note 1)
- This is a port for external operator, Modbus connection, or ProDrioveNext
(RS485/operator changeover switch must be operated) before Power ON. In
case of Modbus communication, it is necessary to set the changeover switch
and parameter (C070). Display of NES1-OP will be according to the parameter
set of b150 continuiously, if the external operator is connected while the
dedicated operator (NES1-OP) is integrated. Note2)
