Reference parameters/normalizations

Reference values, corresponding to 100%, are required for the display of units as

percentages. These reference values are entered in parameters p2000 to p2007. They are

computed during the calculation through p0340 = 1 or in STARTER during drive

configuration. After calculation in the drive, these parameters are automatically protected via

p0573 = 1 from boundary violation 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.

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

After the offline drive configuration, the reference parameters are preset. You can call the

configuration of these parameters via the menu path "Drive > Configuration". On the

"Disabled list" tab, the parameters can be changed and protected.

If the reference values (p2000 to p2007) are changed offline in STARTER, it can lead to limit

violations of the parameter values, which cause alarms or faults when loading to the drive
