Perform frequency setting by analog current input

An external current source is connection to the frequency inverter for setpoint default setting.
● Switch terminal STF (STR)-PC on to give a start command.
● Turn the AU signal on.
● Pr. 79 "Operation mode selection" must be set to "2" (external operation mode).

NOTE For the analog current input (0/4 to 20mA) to become effective for setpoint default setting, the AU
signal on the AU terminal must be activated. This is done, for example, by means of a bridge as
shown in Fig. 5-29.
