Hitachi-America's SJ700B Industrial AC VFD
SJ700B industrial ac VFD's control algorithm enables 120% of full-torque at 0 Hz in sensorless vector control mode, and 150% torque at 0.5 Hz in sensorless vector operation mode. Closed-loop full vector control mode is possible via an optional board. Application integration features include EzSQ built-in programming function that provides the functionality of a PLC built into the inverter. Other features include micro-surge voltage suppression to protect the motor winding insulation, advanced trip avoidance functions, PID, built-in EMC filters and more.
