3.1 Operation
This inverter requires two different signals in order for the Inverter to operate correctly. The Inverter
requires
both an operation setting and a frequency setting.
The following indicates the details of each method of operation and the necessary instructions for
operation.
(1) Operation setting and a frequency setting by the terminal control.
This is the method by connecting signals from the outside (the frequency setting, the starting switch
etc.)
with the control circuit terminals.
The operation is started when the operation setting (FW, RV) is turned ON while the input power is
turned ON.
NOTE: The methods of the setting frequency with terminal are the voltage setting and the electric
setting.
And they are selective by each system. The control circuit terminal list shows this in detail.
(Necessary things for operation)
[1] The operation setting: switch, relay etc.
[2] The frequency setting: signals from volume or outside (DCO-10V, DC-10-10V, 4-20mA etc.)
(2) Operation setting and frequency setting with the digital operator.
This is the method for operation from the digital operator, which comes equipped with the inverter as
standard, or the remote operator keypad.
When the digital operator sets the operation, the terminals (FW, RV) don’t need to be linked.
And it is possible to select frequency from the digital operator as a method of the frequency setting
too.
