7.2.2 Reference parameters/normalizations
Description
Reference values equivalent to 100% are required in order to express units in percentage
terms. These reference values are entered in parameters p2000 to p2007. They are
computed during the calculation via p0340 = 1 or in STARTER during drive configuration.
After calculation in the drive, these parameters are automatically protected via p0573 = 1
against overwriting through a new calculation (p0340). This eliminates the need to adjust the
references values in a PROFIdrive controller whenever a new calculation of the reference
parameters via p0340 takes place.

Note
If a referenced form is selected and the reference parameters (e.g. p2000) are changed
retrospectively, the referenced values of some of the control parameters are also adjusted to
ensure that the control behavior is unaffected.
Using STARTER offline
Following offline drive configuration, the reference parameters are preset; they can be
changed and protected under Drive → Configuration → "Disabled list" tab.
Note
If the reference values (p2000 to p2007) are changed offline in STARTER, it can lead to
boundary violations of the parameter values, which cause fault messages during loading to
the drive.
