 External operation mode (Pr.79 = "0" (initial value) or "2")
• Select the External operation mode when the start command and the frequency command are applied from a frequency
setting potentiometer, start switch, etc. which are provided externally and connected to the control circuit terminals of the
inverter.
• Generally, parameter change cannot be performed in the External operation mode. (Some parameters can be changed.
Refer to on page 89.)
Pr.77
• When = "0 or 2", the inverter starts up in the External operation mode at power-ON. (To start up the inverter in the
Pr.79
Network operation mode, refer to
• When parameter changing is seldom necessary, setting "2" fixes the operation mode to the External operation mode.
