SJ700B series

SJ700B series - Inverter designed for fans & pumps plus conveyors


  • 11kW-75kW, LFUF, 3-phase 200V
  • 5.5kW-160kW, HFF, 3-phase 400V
  • 7.5kW-160kW, HFUF, 3-phase 400V
High starting torque 150% (90kW and over:120%) at 0.5Hz


  • Sensorless Vector Control so the SJ700B can be applied to constant torque loads where high starting torque is needed
  • On-line/off-line auto-tuning
Long lifetime components & Ease of Maintenance
  • Design lifetime 10 Years or more for DC bus capacitors & Cooling Fan
  • Life time warning function
  • Field replacement of cooling fan(s) and DC bus capacitors (18.5kW and over) can be accomplished in a fraction of the time
  • Move existing L300P logic terminal strip to SJ700B without wiring change
    *SJ700B series standard control terminals are the same as SJ700/SJ300. Output terminal are all open collector type
  • Read L300P parameters via WOP remote operator and write them to SJ700B
Various versatile functions and compact design to save space
  • Sequence operation is realized by downloading to an inverter a program created with Hitachi's ProDriveNext software
  • External components can be simplified or eliminated, resulting in cost-savings
  • EMC filter is built in for all models
  • Dynamic brake circuit is included up to 30kW
  • Over-current suppress functions reduce nuisance tripping
Global standards
  • Conformity to global standards. CE, UL, c-UL, C-Tick approvals
  • Logic input & output terminals are selectable for sink & source logic
  • Input voltage 200V to 240V for 200V class and 380V to 480V for 400V class as standard
  • A serial RS-485 Modbus® RTU port is standard
  • The SJ700B can communicate via DeviceNet™ and PROFIBUS® with optional expansion cards
