GetStatus corresponds to a 2 data bytes LIN in−frame response with a direct ID (type #5).
Where:
ID[5:0]: Dynamically allocated direct identifier. There should be as many dedicated identifiers to this GetStatus command as
there are stepper−motors connected to the LIN bus.
GotoSecurePosition
the stepper−motors to move to the secure position
<SecPos[10:0]>. It can also be internally triggered if
the LIN bus communication is lost, after an initialization
phase, or prior to going into sleep mode. See the priority
GotoSecurePosition corresponds to the following LIN writing frame (type #1).
Where:
HardStop
electrical problem is detected in one or both coils, leading to
shutdown mode. If this occurs while the motor is moving,
the <StepLoss> flag is raised to allow warning of the
LIN master at the next GetStatus command that steps
