: 外部信号 A frequency setting command is entered by inputting a signal* from an
external control device. (*: VI/S3 terminal: 0~(5)10Vdc or 4~20mAdc)
: The operation frequency is set by pressing the or key on the
operation panel or an expansion operation panel (optional).
: The operation frequency is set using the internal potentiometer built into the
inverter. Turning the knob clockwise increases the frequency.
: The operation frequency is set by serial communications with an optional
control device.
: Switching between frequency setting by means of analog signals and that by
means of the internal potentiometer is done by activating or deactivating the
input terminals (multi-function programmable input terminals).
