Application-specific functions
The inverter offers a series of functions that you can use depending on your particular
application, e.g.:
● Switching over units
● Braking functions
● Automatic restart and flying restart
● Basic process control functions
● Logical and arithmetic functions using function blocks that can be freely interconnected
● Calculating the energy saving for fluid flow machines
Refer to the following sections for detailed descriptions.
6.7.1
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.
The following options are available:
●
Changing over the motor standard (Page 278) IEC/NEMA
● Changing over the unit system (Page 279)
●
Changing over process variables for the technology controller (Page 279)
The motor standard, the unit system as well as the process variables can only be changed
with STARTER or Startdrive offline.
