Introduction
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.

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.
