Information about the inverter state (alarms, faults, actual values) can be output via inputs
and outputs and also via the communication interface.
Details on evaluating the inverter state via inputs and outputs are provided in Section
Adapting the terminal strip (Page 73).
The evaluation of the inverter state via the communication interface is realized using the
inverter status word. Details on this are provided in the individual sections of Chapter
Configuring the fieldbus (Page 85).

Unit changover

9.9.2.1

Unit changeover

Description
With the unit changeover function, you can adapt the inverter to the line supply (50/60 Hz)
and also select US units or SI units as base units.
Independent of this, you can define the units for process variables or change over to
percentage values.
Specifically, you have the following options:
● Changing over the motor standard (Page 202) IEC/NEMA (adaptation to the line supply)
● Changing over the unit system (Page 202)
● Changing over units for the technology controller (Page 203)
