Inverter basics

You must have an understanding of parameters in order to configure "inverters".
We will use the belt conveyor example described in Chapter 1 again here. If the motor 
moving the belt conveyor is not rotated smoothly, items on the belt conveyor could 
fall off and break. The motor must be started slowly to ensure that the conveyor 
moves smoothly.
The motor can be rotated smoothly in such a manner by configuring inverter parameters.
This chapter will introduce typically used parameters.
