If the curve is monotonously decreasing, and the phase sequence is EMF phase U –
EMF phase W – EMF phase V (i.e. if the phase sequence of V and W is interchanged), then
according to the "Determining the positive direction of the drive (Page 251)" figure in Chapter
"Parameterizing a motor and encoder", the drive direction is negative (i.e. when viewing the
DE flange the axis is rotating counterclockwise).
