*1:Be careful about Items 5 and 7 in 2.2, “Precautions.”
*2:Due to internal processing timing, inverter-side wait time become 0.5 second longer than the setting value of
*3: and are included the operation time of the relay and the magnet contactor.
In almost all cases, it is not necessary to change these parameter settings.
