15 APPLICATION EXAMPLES
This chapter presents some examples of applications of frequency inverters.
15.1 ANALOG INPUTS APPLICATIONS
In this section some applications that use analog inputs are shown. Figure 15.1 on page 15-1 present some
possible connections. The applications described here require the loading of the factory default (P204 = 5 or 6) for
correct execution.

Figure 15.1: Connections for analog inputs.
The results for equations presented in Chapter 9.1 ANALOG INPUTS in page 9-1 are shown on P018 or P019 or
P020 according availability of analog inputs from the inverter. This value could be used as according set on P231
or P236 or P241 (as available by the inverter).
In case of Speed Reference function selected for analog input (P231 or P236 or 241 = 0, for P221 according
application) this reference are going to be a percentage of maximum frequency (P134).
