27. Leaving <Sleep> state is equivalent to power−on−reset.
28. After power−on−reset, the <Standby> state is entered.
29. A DualPosition sequence runs with a separate set of RAM registers. The parameters that are not specified in a DualPosition command are
30. 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
31. Shutdown state can be left only when <TSD> and <HS> flags are reset.
32. Flags can be reset only after the master could read them via a GetStatus or GetFullStatus command, and provided the physical
33. A SetMotorParam command sent while a motion is ongoing (state <GotoPos>) should not attempt to modify <Acc> and <Vmin> values.
34. Some transitions like <GotoPos> → <Sleep> are actually done via several states: <GotoPos> → <SoftStop> → <Stopped> →
35. Two transitions are possible from state <Stopped> when <Sleep> = ‘1’:
36. <SecEn> = ‘1’ when register <SecPos> is loaded with a value different from the most negative value (i.e. different from 0x400 = “100 0000
37. <Stop> flag allows distinguishing whether state <Stopped> was entered after HardStop/SoftStop or not. <Stop> is set to ‘1’ when leaving
38. Command for dynamic assignment of Ids is decoded in all states except <Sleep> and has no effect on the current state.
39. While in state <Stopped>, if <ActPos> → <TagPos> there is a transition to state <GotoPos>. This transition has the lowest priority,
40. If <StepLoss> is active, then SetPosition, SetPositionShort and GotoSecurePosition commands are not ignored.
Remark: IF <SleepEn> = 0, then the arrow from stopped state to sleep state does not exist.
loaded with the values stored in RAM at the moment the DualPosition sequence starts. <AccShape> is forced to ‘1’ during second motion.
<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.
if not activated yet).
conditions allow for it (normal temperature, correct battery voltage and no electrical or charge pump defect).
This can be done during a DualPosition sequence since this motion uses its own parameters, the new parameters will be taken into account
at the next SetPosition or SetPositionShort command.

state <HardStop> or <SoftStop> and is reset during first clock edge occurring in state <Stopped>.
meaning that <Sleep>, <Stop>, <TSD>, etceteras are first evaluated for possible transitions.
<StepLoss> can only be cleared by a GetStatus or GetFullStatus command.
