Main Features

Congratulations on your purchase of an SJ100 Series Hitachi inverter! This inverter drive features state-of-the-art circuitry and components to provide high performance. The housing footprint is exceptionally small, given the size of the corresponding motor. The Hitachi SJ100 product line includes more than a dozen inverter models to cover motor sizes from 1/4 horsepower to 10 horsepower, in either 230 VAC or 460 VAC power input versions. The main features are:

• 200V and 400V Class inverters

• UL or CE version available

• Sensorless vector control

• Regenerative braking circuit

• Convenient keypad for parameter settings

Model SJ100-004NFU

 

•Built-in RS-422 communications interface to allow configuration from a PC and for field bus external modules.

•Sixteen programmable speed levels

•Motor constants are programmable, or may be set via auto-tuning

•PID control adjusts motor speed automatically to maintain a process variable value

The design in Hitachi inverters overcomes many of the traditional trade-offs between speed, torque and efficiency. The performance characteristics are:

•High starting torque of 200% rating or greater

•Continuous operation at 100% torque within a 1:10 speed range (6/60 Hz / 5/50 Hz) without motor derating

•Fan has ON/OFF selection to provide longer life for cooling fan (on models with fan)
