â0â = charge pump OK
â1â = charge pump failure
reset only after GetFullStatus
<OVC1> or <OVC2> or <open circuit 1> or
<open circuit 2> or <CPFail>
resets only after GetFullStatus1
â0â = open
â1â = close
âx00â = Stop
â001â = inner motion acceleration
â010â = inner motion deceleration
â011â = inner motion max. speed
â101â = outer motion acceleration
â110â = outer motion deceleration
â111â = outer motion max. speed
â1â = over current
reset only after GetFullStatus1
â1â = over current
reset only after GetFullStatus1
â0â if SecPos = â100 0000 0000â
â1â otherwise
â1â = step loss due to under voltage, over current
or open circuit
â1â = Vbemf > Average + DeltaThr
â1â = Vbemf < Average â DeltaThr
â1â = Vbemf > AbsThr
Stall detected
â00â = normal temperature range
â01â = low temperature warning
â10â = high temperature warning
â11â = motor shutdown
â1â = shutdown (> 155°C typ.)
reset only after GetFullStatus1 and if
<Tinfo> = â00â
â1â = over temp (> 145°C)
reset only after GetFullStatus1 and if
<Tinfo> = â00â
â0â = Vbb > UV2
â1â = Vbb ⤠UV2
reset only after GetFullStatus1
Set at â1â 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 â0â with a
GetFullStatus1 command.
