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. The program is developed on a PC and then downloaded to the inverter using the simple to use EzSQ software provided at no charge.

The SJ700 also incorporates true servo-like position control, offering a low-cost motion control solution. Mated with a general-purpose induction motor with an encoder, the SJ700 is given a position command, speed command, and acceleration/deceleration times. The shaft moves from position A to position B following the defined profile and then maintain the shaft in servo lock status.
