• When the an analog input is set to “Auxiliary frequency 2” (H3-02, H2-06, or H2-10 = 3), then the value set to this
input will be used as the Multi-Step Speed 3 instead of the value set to parameter d1-03. If no analog inputs are set for
“Auxiliary frequency 2”, then d1-03 becomes the reference for Multi-Step Speed 3.
The different speed references can be selected as shown in Tab le 5.17. Figure 5.42 illustrates the multi-step speed
selection.
