Set to ‘1’ after power-up or after a micro-cut in the supply
voltage to warn that RAM contents may have been lost.
Is set to ‘0’ after GetFullStatus1 command.
Set to ‘1’ if an over current in coil #1 was detected. Is set to ‘0’
after GetFullStatus1 command.
Set to ‘1’ if an over current in coil #2 was detected. Is set to ‘0’
after GetFullStatus1 command.
Set to ‘1’ when under voltage, over current or over temperature
event was detected. Is set to ‘0’ after GetFullStatus1
command. SetPosition and GotoSecurePosition commands
are ignored when <StepLoss> = 1
‘0’ if SecPos = “100 0000 0000”
‘1’ otherwise
Set to ‘1’ if open circuit or a short was detected, (<OVC1> or
<OVC2>). Is. Is set to ‘0’ after GetFullStatus1 command.
Indicates the chip temperature
“00” = normal temperature
“01 = low temperature warning
“10” = high temperature warning
“11” = motor shutdown
Set to one if temperature raises above 145 °C. Is set to ‘0’
after GetFullStatus1 command.
Set to one if temperature raises above 155° C. Is set to ‘0’
after GetFullStatus1 command and Tinfo = “00”.
Indicates the actual behavior of the position controller.
“000”: Actual Position = Target Position; Velocity = 0
“001”: Positive Acceleration; Velocity > 0
“010”: Negative Acceleration; Velocity > 0
“011”: Acceleration = 0 Velocity = maximum pos Velocity
“100”: Actual Position /= Target Position; Velocity = 0
“101”: Positive Acceleration; Velocity < 0
“110”: Positive Acceleration; Velocity < 0
“111”: Acceleration = 0 Velocity = maximum neg Velocity
Indicates the status of the external switch.
‘0’ = open
‘1’ = close
‘0’ charge pump OK
‘1’ charge pump failure
