Introduction
Main Features Congratulations on your purchase of an SJ300
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 SJ300 product line includes
more than twenty inverter models to cover motor
sizes from 1/2 horsepower to 200 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
Sensorless vector control
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
Motor constants are programmable, or may be set
via auto-tuning
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:
High starting torque of 150% rating or greater
Continuous operation at 100% rated torque
within a 1:10 speed range (6/60 Hz / 5/50 Hz)
without motor derating
Models from 0.4–11kW (1/2 to 15hp) 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 sensor feedback
Braking resistors
Radio noise filters
CE compliance filters
Additional factory I/O network interface cards
