Possible with SJ700 Series
High performance, powerful functions,
yet user friendly.
Inverter control by Built-in
Programming function
Sequence operation is realized by downloading to an inverter a
program created with Hitachi's EzSQ software.
Tailor inverter operation to meet changing process
requirements, and replace separate PLCs in some cases.
By simplifying or eliminating external hardware, signficant cost
savings can be achieved.
Password function is incorporated to provide security for
proprietary program data against loss or unauthorized
modification.

1
Easy setup of motor constants
Ideal for applications which need high torque, such as
cranes, extruders and lifts.
Higher internal calculation speed improves current control
performance.
Over-current suppress and Over-voltage suppress functions
avoid inverter trip during acceleration and deceleration.

Position Control Function
The SJ700, with optional feedback board installed, together
with an encoder-equipped motor can perform position control.
For many applications, suitable performance can be
achieved at a lower cost than servo systems.
Based on your four motion parameters (position command,
speed command, acceleration time and deceleration time),
the SJ700 will move an object from original position A to
target position B.
After the movement,
the inverter keeps servo
lock status.
DC Bus AVR Function
During Deceleration
The SJ700 controls deceleration time so that the DC bus
voltage does not exceed the over-voltage trip level, providing
trip-less operation during deceleration.
