Where :
( * ) According to parity computation
Broad: If broad = ‘0’ all the stepper motors connected to the LIN bus will reset to default.
SetDualPosition
This command is provided to the circuit by the LIN master
in order to perform a positioning of the motor using two
different velocities. See Section Dual Positioning. After
Dual positioning the internal flag “Reference done” is set.
Note : This sequence cannot be interrupted by another
positioning command.
command is issued, the circuit will enter in deadlock state.
Therefore, the application should check the actual position
by a GetPosition or a GetFullStatus command
prior to start a dual positioning. Another solution may
consist of programming a value out of the stepper motor
range for Pos1[15:0] . For the same reason
Pos2[15:0] should not be equal to Pos1[15:0].
Important : If for some reason
ActPos equals
Pos1[15:0] at the moment the SetDualPosition
SetDualPosition corresponds to the following LIN writing frame with 0x3C identifier (type #4).
