SJ - 300 Series ( Invertor)
The new SJ300 Inverter are among the most powerful of their class. Hitachi's unique "Advanced Sensorless Vector Control" (ASLV; patent pending) offers 200% starting torque and full torque at zero Hz – without feedback. The integrated Hitachi 32-bit SuperH RISC processor delivers the dynamic response needed for high-end applications.

To compensate possible temperature fluctuations within the motor, which might adversely affect smooth control of the motor, an online/offline motor-autotuning function is included. A newly developed internal control process leads to drastically reduce any rotational fluctuation at low speed, which enhances process stability and precision.
