Notes:
1
After Power on reset, the Shutdown state is entered. The Shutdown state can only be left after a GetFullStatus1
command (so that the Master could read the <VddReset> flag).
2
A RunInit sequence runs with a separate set of RAM registers. The parameters which are not specified in a RunInit
command are loaded with the values stored in RAM at the moment the RunInit sequence starts. AccShape is forced to
‘1’ during second motion even if a ResetToDefault command is issued during a RunInit sequence, in which case
AccShape at ‘0’ will be taken into account after the RunInit sequence. A GetFullStatus1 command will return the
default parameters for Vmax and Vmin stored in RAM.
3
Shutdown state can be left only when <TSD> and <HS> flags are reset.
4
Flags can be reset only after the master could read them via a GetFullStatus1 command, and provided the physical
conditions allow for it (normal temperature, correct battery voltage and no electrical or charge pump defect).
5
A SetMotorParam command sent while a motion is ongoing (state GotoPos) should not attempt to modify Acc and
Vmin values. This can be done during a RunInit sequence since this motion uses its own parameters, the new
parameters will be taken into account at the next SetPosition command.
6
<SecEn> = ‘1’ when register SecPos is loaded with a value different from the most negative value (i.e. different from
0x400 = “100 0000 0000”)
