Our Hitachi SJ700(D) can be used for both heavy and normal duty applications thanks to its dual rated (constant/variable) high torque performance (200% @ 3Hz). The SJ700(D) series can drive both induction motors (IM) and permanent magnetic motors (PM).

Hitachi's SJ700(D) position control function offers servo-like performance allowing for automatic speed control according to a load situation for applications such as cranes or a conveyor. This drive is easy to setup and operate by standard keypad or optional PC-based configuration software

The SJ700(D) can perform up to 5 tasks independently.

The Hitachi SJ700(D) series replaced the SJ700B series. It also replaced the SJ700 series for drives below 200hp. For drives higher than 200hp, please see the SJ700 series.

Our drives are rated for amps, please check amp rating when sizing for variable torque.
