Introduction

A motor control system will obviously include a motor and inverter, as well as fuses for
safety. If you are connecting a motor to the inverter on a test bench just to get started,
that’s all you may need for now. But a fully developed system can also have a variety of
additional components. Some can be for noise suppression, while others may enhance
the inverter’s braking performance. The figure below shows a system with several
possible optional components, and the table gives part number information.

NOTE: The Hitachi part number series for
accessories includes different sizes of each part
type, specified by the –x suffix. Hitachi product
literature can help match size and rating of the
your inverter to the proper accessory size.

Each inverter accessory comes with its own
printed instruction manual. Please refer to those
manuals for complete installation details. This
chapter gives only an overview of these optional
system devices.
