18 Actual Values
The various control functions and methods include electrical control variables and
various calculated actual values of the machine or system. The different actual values
can be read out for operational and error diagnosis via a communication interface or
in the VAL menu branch of the operating unit.
18.1 Actual Values of the Frequency Inverter
The modular hardware of the frequency inverter enables application-specific adapta-
tion. Further actual value parameters can be displayed as a function of the selected
configuration and the installed expansion cards.
