Ic Speed Profile; Overview Of Ic Speed Profile - Danfoss iC7 Motion Series Application Manual

Application Guide | iC7 Series Motion
See Figure 24 for the basic state transition diagram, where control bits 0–3 control the transitions and the corresponding status bit
indicates the actual state. The black dots indicate the priority of the control signals. Fewer dots indicate lower priority, and more dots
indicate higher priority.
The general state diagram is defined in the PROFIdrive standard.

Overview of iC Speed Profile

2.14.1
The iC speed profile is used with the iC7 series. The iC speed profile differs from the PROFIdrive profile, because it does not have a State
Machine. It is only controlled by the actual state 1/0 of the control bits, not the sequence in which they are manipulated.
