4.3.5 Position Limit Enforcement

Description
Determines whether position commands beyond the detected pan axis limits
are allowable. The default is pan position limits are enabled (i.e., enforced).
message and are not executed. In enabled limit mode, limits are only reached
when the unit has lost synchrony and this error condition requires a unit reset
(see Section 4.5.1). When a limit is reached, a "!P" is printed to the host serial

limits are disabled.
