Where:
SetPositionShort
LIN Master to drive one, two or four motors to a given
absolute position. It applies only for half stepping mode
(StepMode[1:0] = “00”) and is ignored when in other
stepping modes. See Positioning for more details.
SetPositionShort can only be used with a network
Two different cases must be considered, depending on the programmed value of the ADMbit in the OTP memory.
The priority encoder table (See Priority Encoder) describes the cases where a SetPositionShort command will be
ignored.
SetPositionShort corresponds to the following LIN writing frames:
Where:
Table 55. SetPosition WRITING FRAME TYPE #4
Table 56. SetPositionShort WRITING FRAME TYPE #2
Adn[6:0]: Motor #n physical address (n ∈ [1,2]). Posn[15:0]: Signed 16−bit position set−point for motor #n.
This command is provided to the circuit by the
The physical address is coded on 4 bits, hence
(*) According to parity computation
Broad: If broad = ‘0’ all the stepper motors connected to the LIN bus will go to Pos[10:0].
ID[5:0]: Dynamically allocated identifier to two data bytes SetPositionShort command.

implementing a maximum of 16 slave nodes. These 4 bits
are corresponding to the bits PA[3:0] in OTP memory. For
SetPositionShort operation: It is recommended to set
HW0 and HW1 to ’1’. If the ADM bit is set to ’1’ the PA0
bit in OTP has to programmed to ’1’. If the ADM bit is set
to ’0’, HW2 has to be set to ’1’.
