3-2 Operation Method
3-2 Operation Method
To operate the Inverter, two commands are required including a RUN command and frequency reference. Take note that the Inverter does not operate if only one of these commands is issued, such as when a RUN command is issued but not a frequency reference (0 Hz setting), or a frequency reference is issued but not a RUN command.
