“x00” = Stop
“001” = inner motion acceleration (CW)
“010” = inner motion deceleration (CW)
“011” = inner motion max. speed (CW)
“101” = outer motion acceleration (CCW)
“110” = outer motion deceleration (CCW)

‘0’ if <SecPos> = “100 0000 0000”

Resets only after Get(Full)Status
Set at ‘1’ after power of the circuit. If this was
‘1’
due to a supply micro−cut, it warns that the
RAM contents may have been lost; can be
reset to ‘0’ with a GetStatus or a
Get(Full)Status command.
