 Usage example 1 ··· 3-wire operation (one-push operation)
Use the 3-wire operation function to operate the inverter, maintaining operation without using the sequence circuit
by inputting an external signal (reset logic signal).

Forward run (F) : Pressing forward run (F) rotates forward at
the specified frequency command value.
Reverse run (R) : Pressing reverse run (R) rotates in reverse
at the specified frequency command value.
HD (S2): Pressing HD (S2) decelerates and stops.

Note 1) Set  =  (ST: standby) and  =  (terminal board) for 3 wire operation. Assign HD
(operation hold) to any input terminal at input terminal selection. When assigning the S2 terminal
as shown above, set  =  (HD: operation hold).
Note 2) If the terminals are ON before turning on the power, terminal input is ignored when the power is
turned ON. (Prevents sudden movements.) After turning the power ON, turn terminal input ON
again.
Note 3) When HD is OFF, F and R are ignored even when ON. R does not operate even if it's ON when
HD is ON. Likewise in this state, F does not operate even if it's ON. Turn F and R OFF and then
turn them ON.
Note 4) During 3 wire operation, sending the jog run mode command stops operation.
