An improved Sensorless Vector (SLV) control algorithm enables the
SJ700 to develop more than 150% starting torque at 0.3 Hz. Using
Hitachi’s unique “0 Hz Domain” open-loop control mode, the SJ700 can
develop 130% torque at 0 Hz, ideal for vertical lift applications. At
the same time, Hitachi has greatly simplified the autotuning process,
making commissioning trouble-free. The SJ700’s Easy Sequence ( EzSQ)
is like having an Industrial Control System (PLC) built into the
inverter. In many cases, the need for a separate PLC can be
eliminated. The SJ700 also features patented Micro Surge Voltage
suppression, advance trip avoidance functions, configurable sink/source
logic on I/O, and much more.
Large capacity AC drives
Hitachi’s high-capacity SJ700 Series of inverters extends their model range up to 500 hp.
