(3) Method to perform driving in FW/RV teraminal and perform frequency setting in volume resistor
This is the operation method using Run command is given by intelligent input terminal such as
FW(RV) function & Frequency setting is given by analog input such as O-L voltage. If you don't
need to change such as Accel&Decel time, optional Operator is not required.) Below diagram is to
set the external Freq. setting connecting H-O-L volume to supply O-L voltage.

* One of the following is required when changing parameters on NE-S1 series inverters.
a) Dedicated operator (NES1-OP) b) Digital operator c) 5-line LCD operator
d) Modbus e) PC programming tool (ProDriveNext)

Note)
The above is a method to perform
analog input(O/OI) by voltage input. It
is necessary for SW6 on the board to
be set for voltage input(default). →
