RunVelocity
This command is provided to the circuit by the
LIN Master in order to put the motor in continuous motion
state. Note: in this mode (RunVelocity), the shaft bit has no
impact on the direction of movement.
Note: The dynamic ID allocation has to be assigned to
‘General Purpose 2 Data bytes’ ROM pointer, i.e. ‘0000’.
The command is decoded only from the command data.
Note: Continuous LIN communication is required. If not,
Lost ? LIN is detected and an autonomous motion will start.
See also LIN lost behavior .
RunVelocity corresponds to the following LIN writing frames (type #1).
