Industry-leading Levels of Performance
High starting torque of 200% or greater achieved
1
by sensorless vector control
Integrated auto-tuning function for easy sensorless vector control
realizes high torque suitable for applications requiring it such as crane
hoists, lifts, elevators, etc.

– Fluctuation is 1/2* compared with the previous model. –
Speed regulation at low speed has been drastically improved to
enhance process stability and precision.
• Frequency commanded by the inverter: 0.5Hz.
• Motor: Hitachi's standard 3-phase 5.5kW 4-pole totally enclosed type motor.

Trip avoidance functions
.
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.
