SJ700 Series AC Variable Speed Drives

Upgrade of the SJ700B Series - 
Hitachi's SJ700 Series outperforms on performance, capabilities and functions of its predecessor, the Hitachi SJ700B Series. The SJ700 Series comes with improved sensorless vector (SLV) control algorithm, which allows the SJ700 Series to develop 150% torque at 0.5 Hz, ideal for a wide range of applications. Another key upgrade in the SJ700 Series is the addition of Hitachi's EzSQ (Easy Sequence) built-in programming function, which provides the functionality of a PLC built into the inverter.
