3-1 Operation Method
This Inverter has the following operation methods that are selected by the RUN command/
frequency reference settings.
The features and the requirements for each operation method are also given below:
To enter the RUN command/frequency reference via the Digital Operator
This action operates the Inverter via a key sequence of the standard or optional Digital Operator.
When operating the Inverter only via the Digital Operator, the Inverter does not need to be
connected to the control circuit terminal block.
To enter the RUN command/frequency reference from the control circuit terminal block
This action operates the Inverter by connecting the external signals (from the frequency setting
device, starting switch, etc.) to the control circuit terminal block.
The operation starts by turning ON the RUN command (FW, RV) while the input power supply is
turned ON.
Note: that the frequency can be set using a voltage signal or a current signal from the control circuit
terminal block, which can be selected according to the system. For details, refer to "Control Circuit
Terminal" (page 2-6).
(Requirements for operation)
• RUN command: Switch, Relay etc.
• Frequency reference: External signal (e.g. 0 to 10 V DC, -10 to 10 V DC, 4 to 20 mA)
To enter the RUN command/frequency reference in a combination of Sources
from the Digital Operator and the control circuit terminal block
The RUN command/frequency reference sources can be selected individually from the Digital
Operator as well as the control circuit terminal block.
