5.2.3 Define the load case, calculate the maximum torque, select the motor
The motor-specific limiting curves are used as basis when selecting a motor.
These define the torque characteristic with respect to speed and take into account the motor
limits based on the line supply voltage and the function of the infeed.

The motor is selected on the basis of the load specified by the application. Different
characteristics must be used for different loads.
The following operating scenarios have been defined:
● Load duty cycles with constant on period
● Load duty cycles with varying on period
● Duty cycle, variable
