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 accesso-
ries includes different sizes of each part type, 
specified by the –x suffix. Hitachi product litera-
ture can help match size and rating of 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.
