*1 -> If each terminal is turned ON before the power is turned ON, it is very dangerous because sudden
movement occurs. Therefore, the input terminal ON signal is ignored at power on. After power on, turn
ON the input terminal again.
*2 -> Turn ON 3-wire operation hold/stop(HD), and then Fwd run (F) or Rev run (R).
Even if Fwd run or Rev run is turned ON while 3-wire operation hold/stop is OFF, the signal will be
ignored. Even if 3-wire operation hold/stop is turned ON while Rev run is ON, operation will not occur.
Even If Fwd run is turned ON in that state, operation will not occur. Turn OFF Fwd run and Rev run,
and then turn ON Fwd run or Rev run.
The input terminal function of 3-wire operation hold/stop is held only for Fwd run (F) and Rev run
(R). Keep in mind that the other functions are not held when Fwd run or Rev run is used in
combination of any other function. For example, when Fwd run and Preset speed switching 1 (SS1)
are assigned, Fwd run is held, but not Preset speed switching 1.
• If the jog run command is input during 3-wire operation, operation will stop.
Memo
• Keep in mind that DC braking continues even if a run command is input during DC braking.
