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 

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
