Programming [EzSQ: Easy Sequence] function

Inverter control by Built-in Programming function

Simple sequence operation is realized by downloading to an inverter the program created by programming soft EzSQ.
It is also possible to automatic speed control according to a load situation like a swift lift function for crane or a conveyor, and to operate.
Since an external circuit can be simplified, a control board is made small and a cost cut can be aimed at.
