Comment
‘0’ = charge pump OK
‘1’ = charge pump failure
reset only after GetFullStatus
<OVC1> or <OVC2> or <open circuit 1> or
<open circuit 2> or <CPFail>
resets only after GetFullStatus1
‘0’ = open
‘1’ = close
“x00” = Stop
“001” = inner motion acceleration
“010” = inner motion deceleration
“011” = inner motion max. speed
“101” = outer motion acceleration
“110” = outer motion deceleration
“111” = outer motion max. speed
‘1’ = over current
reset only after GetFullStatus1
‘1’ = over current
reset only after GetFullStatus1
‘0’ if SecPos = “100 0000 0000”
‘1’ otherwise
‘1’ = step loss due to under voltage, over current
or open circuit
‘1’ = Vbemf > Average + DeltaThr
‘1’ = Vbemf < Average – DeltaThr
‘1’ = Vbemf > AbsThr
Stall detected
“00” = normal temperature range
“01” = low temperature warning
“10” = high temperature warning
“11” = motor shutdown
‘1’ = shutdown (> 155°C typ.)
reset only after GetFullStatus1 and if
<Tinfo> = “00”
‘1’ = over temp (> 145°C)
reset only after GetFullStatus1 and if
<Tinfo> = “00”
‘0’ = Vbb > UV2
‘1’ = Vbb ≤ UV2
reset only after GetFullStatus1
Set at ‘1’ after power-up of the circuit. If this was
due to a supply micro-cut, it warns that the RAM
contents may
have been lost; can be reset to ‘0’ with a
GetFullStatus1 command.
