The SJ700 controls deceleration time so that the DC bus voltage does not exceed the over-voltage trip level, providing trip-less operation during deceleration. Over-current suppress and Over-voltage suppress functions avoid inverter trip during acceleration and deceleration. Higher internal calculation speed improves current control performance. HITACHI SJ700 MODEL SJ700D-055LFUF3 7.5 HP 200-240 VOLT 3/PH 24 CT/ 30 VT- FREE GROUND SHIPPING. Over current & Improved Sensorless Vector Control and Auto Tuning voltage suppress function After the movement, the inverter keeps servo lock status. Based on your four motion parameters (position command, speed command, acceleration time and deceleration time), the SJ700 will move an object from original position A to target position B. The SJ700, with optional feedback board installed, together with an encoder-equipped motor can perform position control.įor many applications, suitable performance can be achieved at a lower cost than servo systems.

The SJ700 inverter drive features state-of-the-art circuitry and components to provide high performance as well as high precision sensorless vector control via autotuning. Description Additional information Description.
