Introduction

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:

• 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:

• V/F (volts-per-hertz) control algorithm, selectable for either constant or reduced

torque loads

• Output frequency range from 0.5 to 360 Hz

• Continuous torque operation at 100% within a 1:10 speed range (6/60 Hz / 5/50 Hz)

without motor derating

A full line of accessories from Hitachi is available to complete your application:

• Digital remote operator keypad

• Dynamic braking unit

• Radio noise filters and EMI filters (shown below)

• CE compliance filters

• DIN rail mounting adapter (35mm rail size)
