ACS800 Actual Speed Scaling in Scalar Mode Application Note

This document explains how the actual speed scaling on the fieldbus works for an ACS800 drive when parameter 99.04 is set to Scalar mode, noting that the scaling is based on parameter 20.02 MAXIMUM SPEED even though it is not logically applicable. It provides a step-by-step procedure to adjust the speed scaling by temporarily switching to DTC mode to recalculate the maximum speed value based on the desired maximum frequency.
