4.2.2.27. "Set Minimum Track Rate" command

This command sets the minimum track rate that is allowed to be set with a Proprietary Track (0x30) or Motion Activated
Proprietary Track (0x34).
The minimum track that can be set in any case with one of the above commands is "2" which is interpreted as 2.5 minutes (all
other values that may be sent are interpreted as the actual number of minutes).
This command will not be NAK'd for values < 2 but setting this "minimum" value to less than 2 shall simply enforce the
absolute minimum of 2.
The factory value for this shall be "0".
