Industry-leading Levels of Performance
High starting torque of 200% or greater achieved
by sensorless vector control
(
when sized for heavy duty
).
Speed regulation at low-speed is greatly improved.
–
Fluctuation is 1/2* compared with the previous model.

Integrated auto-tuning function for easy sensorless vector control
realizes high torque suitable for applications requiring it such as crane
hoists, lifts, elevators, etc.
Minimum time deceleration function, over-current suppress function
and DC bus AVR function are incorporated. The functions reduce
nuisance tripping. Improved torque limiting/current limiting function
enables a load limit to protect machine and equipment.
Speed regulation at low speed has been drastically improved to
enhance process stability and precision.

Auto-tuning to perform sensorless vector control can now be easily done.
(Example of WJ200-055LF)
• Frequency commanded by the inverter: 0.5Hz.
• Motor: Hitachi's standard 3-phase 5.5kW 4-pole totally enclosed type motor.
Example of Hitachi's standard motor. (7.5kW 4-pole)
2.3 sec. reduction of deceleration time without a braking
resistor is achieved when the function is active.
