SetStallParam
This command sets the motion detection parameters and
the related stepper ? motor parameters, such as the minimum
acceleration and step mode. See Motion detection for the
meaning of the parameters sent by the LIN Master.

SetMotorParam
This command is provided to the circuit by the LIN master
to set the values for the stepper motor parameters (listed
below) in RAM. Refer to RAM Registers to see the meaning
of the parameters sent by the LIN master.
Position Controller). Therefore the application should not
change other parameters than <Vmax> and <Vmin> while
a motion is running, otherwise correct positioning cannot be
guaranteed.
Important: If a SetMotorParam occurs while a motion
is ongoing, it will modify at once the motion parameters (see
SetMotorParam corresponds to the following LIN writing frame with 0x3C identifier (type #4).
