Hitachi SJ700 Series AC Variable Speed Drive

Manufacturer: Hitachi

Hitachi SJ700 Series VFDs reasserts its technological leadership with an improved sensor-less vector (SLV) control algorithm that enables the SJ700 to develop more than 200% starting torque at 0.3 Hz. The SJ700 can develop 150% torque at 0 Hz, which is ideal for vertical lift applications, using Hitachi’s unique "0 Hz Domain" open-loop control mode.

Hitachi has also greatly simplified the auto-tuning process, making commissioning trouble-free. Enhancement in the SJ700 is Hitachi’s EzSQ (Easy Sequence) built in programming function. It is similar to having a PLC built into the inverter! In many cases, the need for a separate PLC can be eliminated.
