14.11.3.2 Reference values
Overview
There is a reference value in the converter for most parameters with a physical unit.
Description of function
When the per-unit representation [%] is set, the converter scales the physical quantities based
on the respective reference value.
If the reference value is changed, the signi󹪝cance of the scaled values also changes. Example:
• Reference speed = 1500rpm → 󹪝xed speed=80% corresponds to speed = 1200rpm
• Reference speed = 3000rpm → 󹪝xed speed=80% corresponds to speed = 2400rpm
The parameter list provides the associated reference value for the scaling for each parameter.
For example, r0065 is scaled with reference value p2000.
If no scaling is speci󹪝ed in the parameter list, the converter always expresses the parameter
unscaled.
