7-3 Description of Functions
●
When F1101=2 (external terminal), the input signals of control terminals FR and RR are active. When FR is ON, the
inverter will drive to forward. When RR is ON, the inverter will drive to reverse. Moreover if FR and RR are
simultaneously input during operation, then [Output Frequency Lock] will act. If this is done during accelerating or
decelerating, the change of output frequency will also be locked. And when the output frequency is locked, the
FWD and REV on the operation panel will be lit.

If RREV is ON, then the inverter will drive to reverse revolution from revolution direction command. Therefore if
both input signals FR and RREV are ON at the same time, then the inverter will drive to reverse. If both input
signals RR and RREV are ON at the same time, then the inverter will drive to forward.
●
When F1101=3 (communication), the inverter can operate by communication command. Please refer to section 7-4
to know inverter operation by communication command.
●
When F1101=4 (external terminal(3 wired operation)), the input signals of control terminals RUN , STOP and
FR/RR are active. Another input signals always enable unrelated F1101 setting value. When F1104 set 4, the
inverter can start by changing RUN signal OFF to ON with STOP signal is ON. When STOP signal change to OFF,
the inverter can stop. Revolution direction of the motor can select FR/RR function. If FR/RR is OFF, then
revolution direction is forward. If FR/RR is ON, then revolution direction is reverse.
