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 Get(Full)Status
‘0’ = open
‘1’ = close
<CPFail> or <UV2> or <ElDef> or
<VDDreset>
“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 GetFullStatus
‘1’ = over current
reset only after GetFullStatus
‘0’ if SecPos = “100 0000 0000”
‘1’ otherwise
‘1’ = Sleep mode
reset by LIN command
‘1’ = step loss due to under voltage, over
current or open circuit
‘1’ = Vbemf > Ūbemf + DeltaThr
‘1’ = Vbemf > Ūbemf – DeltaThr
‘1’ = Vbemf > AbsThr
“00” = normal temperature range
“01” = low temperature warning
“10” = high temperature warning
“11” = motor shutdown
‘1’ = shutdown. (> 155°C typ.)
reset only after Get(Full)Status and if
<Tinfo> = “00”
‘1’ = over temp. (> 145°C)
reset only after Get(Full)Status and if
<Tinfo> = “00”
‘0’ = Vbb > UV2
‘1’ = Vbb ≤ UV2
reset only after Get(Full)Status
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
GetStatus or a
GetFullStatus command.
