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.
Password function is added to prevent program information
leaks. This is also useful for unexpected data rewriting or
deletion by operation mistake.
