It is the most convenient and reliable method of drive selection, as the entire torque/speed curve of the ap-
plication is displayed and evaluated here in the curve of the geared motor.
In this chapter, only limit values for specific operating points can be taken into consideration for manual
drive selection.
An explanation of the formula symbols can be found in Chapter Symbols in formulas.
The formula symbols for values actually present in the application are marked with *.
