ResetToDefault will correspond to the following LIN writing frames (type #1).
Where:
SetDualPosition
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.
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).
Where:
Table 49. ResetToDefault WRITING FRAME TYPE #1
Table 50. SetDualPositioning WRITING FRAME TYPE #4
(*) According to parity computation
Broad: If broad = ‘0’ all the stepper motors connected to the LIN bus will reset to default.
This command is provided to the circuit by the LIN master
Broad: If broad = ‘0’ all the circuits connected to the LIN bus will run the dual positioning
Vmax[3:0]: Max velocity for first motion
Vmin[3:0]: Min velocity for first motion and velocity for the second motion
Pos1[15:0]: First position to be reached during the first motion
Pos2[15:0]: Position of the second motion

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
Pos2[15:0] should not be equal to Pos1[15:0].
