29. <ElFlag> = <CPFail> or <UV2> or <ElDef> or <VDDreset>
30. After power−on−reset, the <Standby> state is entered.
31. A DualPosition sequence runs with a separate set of RAM registers. The parameters that are not specified in a DualPosition command are
32. Shutdown state can be left only when <TSD> and <HS> flags are reset.
33. Flags can be reset only after the master could read them via a GetFullStatus1 command, and provided the physical conditions allow
34. A SetMotorParam command sent while a motion is ongoing (state <GotoPos>) should not attempt to modify <Acc> and <Vmin> values.
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 distinguishing whether state <Stopped> was entered after HardStop/SoftStop or not. <Stop> is set to ‘1’ when leaving
37. While in state <Stopped>, if <ActPos> → <TagPos> there is a transition to state <GotoPos>. This transition has the lowest priority,
38. If <StepLoss> is active, then SetPosition and GotoSecurePosition commands are not ignored. <StepLoss> can only be cleared
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 GetFullStatus1 command will return the default
parameters for <Vmax> and <Vmin> stored in RAM.
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 command.
