Main Features

Congratulations on your purchase of an L100 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 L100 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

•V/f (volts-per-hertz) control algorithm, select- able for either constant or reduced torque loads

•Convenient keypad for parameter settings

• Built-in RS-422 communications interface to

Model L100-002NFU

 

allow configuration from a PC and for field

 

bus external modules.

 

•Sixteen programmable speed levels

•Two-step acceleration and deceleration curves

•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:

•Output frequency range from 0.5 to 360 Hz

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