The SJ700 series of inverters expands on the performance, capabilities and functions of the SJ300. The sensorless vector control algorithm enables the drive to develop more than 200% starting torque at 0.3 Hz. It can develop 150% torque at 0 Hz, ideal for vertical lift applications. The auto-tuning process has been simplified and it has an EzSQ built in programming function, which in many cases eliminates the need for a separate PLC.
