Advanced commissioning
6.13 Selecting physical units
Reference variables
There is a reference variable in the converter for most parameters with physical units. When
the referred representation [%] is set, then the converter scales the physical variables based
on the particular reference variable.
When the reference variable changes, then the significance of the scaled value also changes.
Example:
• Reference speed = 1500 rpm → fixed speed = 80 % ≙ 1200 rpm
• Reference speed = 3000 rpm → fixed speed = 80 % ≙ 2400 rpm
For each parameter you can find the associated reference variable for scaling in the List
Manual. Example: r0065 is scaled with reference variable p2000.
If scaling is not specified in the List Manual, then the converter always represents/displays the
parameter unscaled (not normalized).
Groups of units
The parameters associated with the selection of a physical unit, belong to different groups of
units.
You can find the associated group of units in the List Manual for each parameter. Example:
r0333 belongs to unit group 7_4.
An overview of the unit groups and the possible physical units can also be found in the List
Manual.
6.13.3

Technological unit of the technology controller

Options when selecting the technological unit
p0595 defines in which technological unit the input and output variables of the technology
controller are calculated, e.g. [bar], [m³/min] or [kg/h].
Reference variable
p0596 defines the reference variable of the technological unit for the technology controller.
Unit group
Parameters involved with p0595 belong to unit group 9_1.
Further information on this topic is provided in the List Manual.
Special features
You must optimize the technology controller after changing p0595 or p0596.
