Danfoss VLT AutomationDrive FC 360 Design Guide

Bus references are scaled according to the following rules:
l When parameter 3-00 Reference Range is set to [0] Min–Max, 0% reference equals minimum reference, and 100% reference equals
maximum reference.
l When parameter 3-00 Reference Range is set to [1] -Max–+Max, -100% reference equals -maximum reference, and 100% reference
equals maximum reference.
8.3.2.4 Scaling of Analog and Pulse References and Feedback
References and feedback are scaled from analog and pulse inputs in the same way. The only difference is that a reference above or below
the specified minimum and maximum endpoints (P1 and P2 in the following illustration) are clamped while a feedback above or below is
not.
