Hitachi America, Ltd.: High-performance AC drive

The SJ700-2200HFU2 model inverter from Hitachi America’s Industrial Components & Equipment Division has 440 A output current capability to fill the gap at 300-350 hp in the SJ700 series, which now completely covers the range from1/2 to 600 hp.

The SJ700 significantly expands on the performance, capabilities and functions of its predecessor, the SJ300, with an improved vector control algorithm and auto-tuning function that enables the open-loop SJ700 (SLV) to develop more than 200% starting torque at 0.3 Hz. Using Hitachi’s “0 Hz Domain” open-loop control mode, the SJ700 can develop 150% torque near 0 Hz for vertical lift applications. In closed-loop mode with encoder feedback, the SJ700 performance delivers in excess of 100% torque at 0 Hz, according to the company.  Another element in the SJ700 is Hitachi’s EzSQ (Easy Sequence) built-in programming function, which eliminates the need for a separate PLC.
