Programming [Ezsq: Easy Sequence] Function; Emc Filter & Brake Circuit Integrated As Standard - Hitachi SJ700 series Manual

High performance, powerful functions,
yet user friendly.

Programming [EzSQ: easy sequence] function

Inverter control by built-in
programming functions
Custom operation is realized by downloading to an inverter a
user program created with ProDriveNext, Hitachi inverter
configuration 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.
Typical example - Replacing external relay circuit
