SetPositionShort
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
implementing a maximum of 16 slave nodes. These 4 bits
SetPositionShort corresponds to the following LIN writing frames:
Where:
Where:
Table 65. SetPositionShort WRITING FRAME TYPE #2
Table 66. SetPositionShort WRITING FRAME TYPE #2
This command is provided to the circuit by the LIN Master
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.
(*) according to parity computation
ID[5:0]: Dynamically allocated identifier to four data bytes SetPositionShort command.
Adn[3:0]: Motor #n physical address least significant bits (n ∈ [1,2]).
Posn[10:0]: Signed 11−bit position set point for Motor #n (see RAM Registers)
1. Two (2) data bytes frame for one (1) motor, with specific identifier (type #2)
2. Four (4) data bytes frame for two (2) motors, with specific identifier (type # 2)

SetPositionShort it is recommended to set HW0,
HW1 and HW2 to ’1’.
