HITACHI – SJ300 Inverter

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.

• Advanced Sensorless Vector Control (closed/open loop)
• Starting Torque >200%
• Full Torque at 0 Hz
• High-Torque Multi-Motor Operation (with SLV)
• Motor-Autotuning (online/offline)
• Quick-Stop Function
• RS485 and RS422 interfaces
• Global Standards to CE, UL, c-UL, CTick, CSA
• Built-in Potentiometer
• PID Control
• P/PI Control
• Automatic Voltage Regulation
• Motor Thermistor Input
• User Macro Saving
• And many more

For high-dynamic applications, e.g. in the packaging, printing, textile and machine tool industries and for lifts and cranes.
