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
Operates the Inverter via the 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
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 the voltage directive or the current directive from the
control circuit terminal block, which can be selected according to the system. For details, refer to
"Control Circuit Terminal" (page 2-7).
(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)
