Reference parameters/scaling

Reference values, corresponding to 100%, are required to display 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.

Parameters p0514 ... p0519 are provided for scaling purposes when interconnecting BICO

parameters (also see SINAMICS S120/S150 List Manual).

Illustration of conversion with reference values

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
