High performance, powerful functions, yet user friendly.

Programming [EzSQ: Easy Sequence] function

Inverter control by Built-in Programming function

Sequence operation is realized by downloading to an inverter a program created with Hitachi's EzSQ software.

Tailor inverter operation to meet changing process requirements, and replace separate PLCs in some cases.

By simplifying or eliminating external hardware, signficant cost savings can be achieved.

Password function is incorporated to provide security for proprietary program data against loss or unauthorized modification.
