Introduction
Main Features Congratulations on your purchase of an L300P
Series Hitachi inverter! This inverter drive features
state-of-the-art circuitry and components to provide
high performance. The housing footprint is excep-
tionally small, given the size of the corresponding
motor. The Hitachi L300P product line includes
more than twenty inverter models to cover motor
sizes from 2 horsepower to 175 horsepower, in
either 230 VAC or 480 VAC power input versions.
The main features are:
200V Class and 400V Class inverters

STOP control and setting parameters

allow configuration from a PC and for field bus
external modules
Sixteen programmable speed levels

maintain a process variable value
The design of Hitachi inverters overcomes many of
the traditional trade-offs between speed, torque and
efficiency. The performance characteristics are:
Continuous operation at 100% rated torque
within a 1:10 speed range (6/60 Hz / 5/50 Hz)
without motor derating
Models up to and including 11kW and 15kW
(15 and 20hp) have built-in dynamic braking
units
