Hitachi Industrial SJ700B frequency inverter outperforms on performance, capabilities and functions of its predecessor, the Hitachi L300P. The SJ700B Series comes with improved sensorless vector control algorithm, which allows SJ700B series inverters to develop 150% torque at 0.5Hz, ideal for wide range of applications.
1. High starting torque 150% (90kW and over: 120%) at 0.5Hz
1. 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
- 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
- Read L300P parameters via WOP remote operator and write them to SJ700B
- Sequence operation is realized by downloading to an inverter a program created with Hitachi's ProDriveNext software
- External components can be simplified or elimitnated, 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
- 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.
