C.2.79.
POSTOLERANCE
The POSTOLERANCE axis parameter is used to trigger the Position Tolerance FAULT.
If the axis moves less than twice the POSTOLERANCE value within POSTOLTIME
milliseconds, the fault will occur.
This is useful in situations where an axis is commanded to move a distance less than the
POSERRLIMIT and there is a long IAVGTIME specified. This prevents the axis from
running away before the IAVGLIMIT fault occurs. The move length limitation prevents
spurious faults from occurring on moves that are shorter then the POSTOLERANCE
value or axes which are moving at slow velocities. This fault can not occur on virtual
axes.
C.2.80.
POSTOLTIME
The POSTOLTIME axis parameter specifies the time in milliseconds before the
POSTOLERANCE axis parameter generates an axis fault.
C.2.81.
PROFILETIME
The PROFILETIME axis parameter is used only in the profile mode of trajectory
generation, available only to those users programming the machine via the library
functions. It will define the execution time of each profile block, within the profile mode.
See the Library Reference Manual (EDU156) for more information.
C.2.82.
PROFQDEPTH
The profile queue depth parameter indicates the number of motion profile commands in
the queue that are waiting to be executed by the axis.
C.2.83.
PROFQSIZE
The profile queue size parameter indicates the maximum number of motion profile
commands permitted in the motion profile queue.
C.2.84.
RAWPOS
Same as the POS axis parameter, except this parameter indicates the change in axis
position made by Axis Calibration or 2D Axis Calibration.
C.2.85.
RESOLVER
The resolver axis parameter indicates the absolute position of the axis as reported by the
resolver, if present, not the position of the master axis resolver.
C.2.86.
REVERSALMODE
To provide greater positioning accuracy, this axis parameter allows you to specify the
number of machine steps (counts) required to compensate for any backlash present in the
system. Backlash, is the “play” or “slop” in the mechanics, and occurs when a drive screw
changes direction and turns a fixed amount before the load begins to actually move in the
