AMIS ? 30623
LIN Lost Behavior
Introduction
When the LIN communication is broken for a duration of
25000 consecutive frames (= 1,30s @ 19200 kbit/s)
AMIS ? 30623 sets an internal flag called “LIN lost”. The
functional behavior depends on the state of OTP bits
<SleepEn> and <FailSafe> , and if this loss in LIN
Table 35. SLEEP ENABLE SELECTION
communication occurred at (or before) power on reset or in
normal powered operation.
Sleep Enable
The OTP bit <SleepEn> enables or disables the
entering in low ? power sleep mode in case of LIN time ? out.
Default the entering of the sleep ? mode is disabled.
<SleepEn>
0
1
Behavior
Entering low ? power sleep mode is disabled except from <Standby> and <Shutdown>
Entering low ? power sleep mode enabled
Fail Safe Motion
The OTP bit <FailSafe> enables or disables an automatic motion to a predefined secure position. See also Autonomous Motion .
Table 36. FAIL SAFE ENABLE SELECTION
<FailSafe>
0
1
Behavior
NO reference motion in case of LIN – lost
ENABLES reference motion to a secure position in case of LIN–lost (if the device has not been yet referenced
with SetDualPosition)
AMIS ? 30623 is able to perform an Autonomous Motion
to a preferred position. This positioning starts after the
detection of lost LIN communication and depends on:
? the OTP bit <FailSafe> = 1.
? RAM register <SecPos[10:0]> ≠ 0x400
The functional behavior depends if LIN communication
is lost during normal operation (see figure below case A) or
at (or before) startup (case B):
Power Up
OTP content is
copied in RAM
If OTP bit <FailSafe> = 1, the reaction is the following:
If the device has already been referenced, it is assumed
that <ActPos> register contains the “real” actual position.
At LIN – lost an absolute positioning to the stored secure
position SecPos is done (identical to the case, when OTP bit
<FailSafe> = 0).
If the device was not referenced yet, the <ActPos>
register does not contain a valid position. At LIN – lost a
referencing is started using DualPositioning. A first
negative motion of half the positioner range is initiated until
the stall position is reached. The motion parameters stored
in OTP will be used for this. After this mechanical
end ? position is reached, <ActPos> will be reset to zero. A
second motion of 10 Fullsteps is executed to assure that the
motion is really at the end position. After the second motion,
a third motion is executed to the Secure Position also stored
in OTP; if <SecPos> = 0x400, this second motion is not
executed.
B
No
LIN Bus OK
Yes
A
Following sequence will be followed. See Figure 24.
1. <SecPos[10:0]> from RAM register will be
used. This can be different from OTP register if
earlier LIN master communication has updated this.

(Case A: LIN lost during operation and Case B: LIN
lost at startup)
LIN Lost During Normal Operation
If the LIN communication is lost during normal operation,
it is assumed that AMIS ? 30623 is referenced (by Dual
postioning or Resetposition). In other words the <ActPos>
register contains the “real” actual position. At LIN – lost an
absolute positioning to the stored secure position SecPos is
done. This is further called Secure Positioning.
See also Secure Position and command
SetMotorParam .
I. If <SecPos[10:0]> = 0x400: No Secure
Positioning will be performed
II. If <SecPos[10:0]> ≠ 0x400: Perform a
Secure Positioning. This is an absolute
positioning (slave knows its ActPos.
<SecPos[10:0]> will be copied in
<TagPos> )
Depending on <Sleep> AMIS ? 30623 will enter the
<Stop> state or the <Sleep> state. See Table 35.
