4.3.4 Limit Position Queries
Description
Queries return the axis position bounds determined upon unit reset.
Syntax
Query minimum pan position: PN<delim>
Query maximum pan position: PX<delim>
Query minimum tilt position: TN<delim>
Query maximum tilt position: TX<delim>
Example
R *
PN * Minimum Pan position is -3090
PX * Maximum Pan position is 3090
TN * Minimum Tilt position is -907
TX * Maximum Tilt position is 604
LE *
PP3200 ! Maximum allowable Pan position is 3090

4.3.5 Position Limit Enforcement
Description
Determines whether position commands beyond the detected pan and tilt axis
limits are allowable. The default is position limits are enabled (i.e., enforced).
Enabling position limits ensures that all positions within the limits can
be achieved when the load does not extend below the bottom of the load
mounting plate (see Section 3.5). When limits are enabled, commands
outside of the limits return an error message and are not executed. In enabled
limit mode, limits are only be 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 either “!P” or “!T” is printed to indicated which axis limit was hit
(pan or tilt).
When larger operational ranges are required, the limits may be disabled.
Positional commands outside the limits are not rejected when limits are
disabled. Positions outside the limits introduce the possibility that the tilt axis
and load can interfere with the pan axis, so it is important that accessibility of
positions outside the limits be determined.
Syntax
Query the current position limit mode: L<delim>
Enable position limits: LE<delim>
Disable position limits: LD<delim>
