You can operate the inverter by inputting external signals to the control terminals.
The run commands are input to the digital input terminals by the ON/OFF signals.
The frequency commands are input to the analog input terminals by the voltage signals (potentiometer,
etc.), or the current signals. This chapter explains how to set the parameters required to operate the
inverter using external signals and how to assign the functions to the terminals.
You can operate the inverter by external signals.
The parameter setting items vary depending on the operation method. Before setting the parameters, be
sure to check the operation method (how to input run commands and frequency commands).
For operation by communication, refer to "Communication Function Instruction Manual" (E6582143) and
[6. 38].
