Application-specific functions

The inverter offers a series of functions that you can use depending on your particular
application, e.g.:
● Switching over units
● Calculating the energy saving for fluid flow machines
● Braking functions
● Automatic restart and flying restart
● Basic process control functions
● Essential service mode
● Multi-zone control
● Bypass

Unit changeover

Description
Using the unit switchover function, you can switch over parameters and process variables for
input and output to an appropriate system of units: US units, SI units or relative variables as
a %.
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 242) IEC/NEMA
● Changing over the unit system (Page 243)
● Changing over process variables for the technology controller (Page 243)
The motor standard, the unit system as well as the process variables can only be changed
offline.
