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
• U.S. or European version available
• Variable frequency control
• Optional regenerative braking circuit
• Different operator keypads available for RUN/
STOP control and setting parameters
• Built-in RS-422 communications interface to
allow configuration from a PC and for field bus
external modules
• Sixteen programmable speed levels
• PID control adjusts motor speed automatically to
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
• Cooling fan has ON/OFF selection to provide
longer life
A full line of accessories from Hitachi is avail-
able to complete your motor control application.
These include:
• Digital remote operator keypad
• Expansion card for digital inputs
• Braking resistors
• Radio noise filters
• CE compliance filters
• Additional factory I/O network interface cards
