two data bytes LIN writing frame (type #1).
Where:
ResetPosition
to reset <ActPos> and <TagPos> registers to zero. This
can be helpful to prepare for instance a relative positioning.
The reset position command sets the internal flag
“Reference done”.
ResetPosition corresponds to the following LIN writing frames (type #1).
Where:
ResetToDefault
LIN Master in order to reset to whole slave note into the
initial state. ResetToDefault will, for instance, overwrite the
RAM with the reset state of the registers parameters (See
RAM Registers). This is another way for the master to
Table 47. HardStop WRITING FRAME TYPE #1
Table 48. ResetPosition WRITING FRAME TYPE #1
A hardstop command can also be issued by the LIN master for some safety reasons. It corresponds then to the following
(*) According to parity computation
Broad: If broad = ‘0’ all stepper motors connected to the LIN bus will stop
This command is provided to the circuit by the LIN master
(*) According to parity computation
Broad: If broad = ‘0’ all the circuits connected to the LIN bus will reset their <ActPos> and <TagPos> registers
This command is provided to the circuit by the
