26. Leaving sleep state is equivalent to POR.
27. After POR, the shutdown state is entered. The shutdown state can only be left after GetFullStatus command (so that the master could
28. A DualPosition sequence runs with a separate set of RAM registers. The parameters that are not specified in a DualPosition command are
29. The <Sleep> flag is set to ‘1’ when a LIN timeout or a Sleep command occurs. It is reset by the next LIN command (<Sleep> is cancelled
30. Shutdown state can be left only when <TSD> and <HS> flags are reset.
31. Flags can be reset only after the master could read them via a GetStatus or GetFullStatus command, and provided the physical
32. A SetMotorParam command sent while a motion is ongoing (state GotoPos) should not attempt to modify Acc and Vmin values. This can
33. Some transitions like GotoPos → sleep are actually done via several states: GotoPos → SoftStop → Stopped → Sleep (see diagram below).
34. Two transitions are possible from state stopped when <Sleep> = ‘1’:
35. <SecEn> = ‘1’ when register SecPos is loaded with a value different from the most negative value (i.e. different from 0x400 = “100 0000
36. <Stop> flag allows to distinguish whether state stopped was entered after HardStop/SoftStop or not. <Stop> is set to ‘1’ when leaving state
37. Command for dynamic assignment of Ids is decoded in all states except sleep and has not effect on the current state.
38. While in state stopped, if ActPos → TagPos there is a transition to state GotoPos. This transition has the lowest priority, meaning that
39. If <StepLoss> is active, then SetPosition, SetPositionShort and GotoSecurePosition commands are ignored (they will not

if a ResetToDefault command is issued during a DualPosition sequence, in which case AccShape at ‘0’ will be taken into account after
the DualPosition sequence. A GetFullStatus command will return the default parameters for Vmax and Vmin stored in RAM.
