CHAPTER 7
7.1 APPLICATIONSAND 
PROGRAMMING
Below are shown some characteristic curves with the starting torque
behavior of some load types and the recommended type of control
to be used.
PROGRAMMING INFORMATION AND
SUGGESTIONS
This Chapter is useful for setting and programming the start control
type according to the application.
ATTENTION!
Important information about each start control type.
ATTENTION!
For correct parameter setting you must consider the load data and
use Sizing software WEG - SDW, available at WEG Site (http://www.
weg.net).
If this software can not be used, you can follow some practical concepts
described below:
