The SJ300 is one of the most compact drives in its class, but offers an unprecedented array of features built-in, such as 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, PID Control, P/PI Control, Automatic Voltage Regulation,Motor Thermistor Input, User Macro Saving and Global Standards to CE, UL, c-UL, CTick, CSA.

The SJ300 is designed for any application, ideally suited to highly dynamic applications such as packaging, printing, textile, machine tool industries, lifts, cranes, centrifuges, extruders and any application which requires high starting torques or is subject to shock loads. There are seven inputs of which five are programmable, two programmable transistor outputs, one programmable relay output and a dedicated thermistor input terminal. Access to the terminal rails is by removing the lower front case. There is also the option of a variety of fieldbus communications.
