Introduction
Main Features
Congratulations on your purchase
of an SJ200
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 SJ200
includes more than a dozen inverter
models to cover motor sizes from 1/
4 horsepower to 10 horsepower, in
either 240 VAC or 480 VAC power
input versions. The main features
are:
• 200V and 400V Class inverters
• US or EU versions available (country-specific input voltage range and default values)
• New intelligent sensorless vector control (iSLV)—auto-tuning no longer necessary
• Dynamic braking with external resistor
• Convenient, removable keypad for parameter settings, can be mounted on panel door
• Built-in RS-485 MODBUS RTU as standard
• New current limit function
• Sixteen programmable speed levels
• 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:
• High starting torque of 200% at 1Hz
• Continuous operation at 100% torque within a 1:10 speed range (6/60 Hz / 5/50 Hz)
without motor derating
• Fan has ON/OFF selection to provide longer life for cooling fan (on models with fan)
A full line of accessories from Hitachi is available to complete your motor application:
• Digital remote operator keypad
• Panel-mount keypad bezel kit and DIN rail mounting adapter (35mm rail size)
• Dynamic braking unit with resistors
• Radio noise filters
• CE compliance filters
