Motion Object Attributes 281
Position Cam Pending Status
The Position Cam Pending Status bit attribute is set if a Position Cam motion
profile is currently pending the completion of a currently executing cam
profile. This would be initiated by executing an MAPC instruction with
Pending execution selected. As soon as the current position cam profile
completes, initiating the start of the pending cam profile, the Position Cam
Pending bit is cleared. This bit is also cleared if the position cam profile
completes, or superseded by some other motion operation.
Time Cam Pending Status
The Time Cam Pending Status bit attribute is set if a Time Cam motion profile
is currently pending the completion of a currently executing cam profile. This
would be initiated by executing an MATC instruction with Pending execution
selected. As soon as the current time cam profile completes, initiating the start
of the pending cam profile, the Time Cam Pending bit is cleared. This bit is
also cleared if the time cam profile completes, or superseded by some other
motion operation.
Gearing Lock Status
The Gearing Lock Status bit attribute is set whenever the slave axis is locked to
the master axis in a gearing relationship according to the specified gear ratio.
The clutch function of the gearing planner is used to ramp an axis up, or down,
to speed in a gearing process (MAG with Clutch selected). During the intervals
where the axis is clutching, the Gearing Lock Status bit is clear.
Position Cam Lock Status
The Position Cam Lock Status bit attribute is set whenever the master axis
satisfies the starting condition of an active Position Cam motion profile. The
starting condition is set by the Start Control and Start Position parameters of
the MAPC instruction. If the current position cam profile ends, or is
superseded by another motion operation, the Position Cam Lock bit is cleared.
In uni-directional master direction mode, the Position Cam Lock Status bit
clears when moving in the “wrong” direction and sets when moving in the
correct direction.
Master Offset Move Status
The Master Offset Move Status bit attribute is set if a Master Offset Move
motion profile is currently in progress. As soon as the Master Offset Move is
complete or superseded by some other motion operation, the Master Offset
Move Status bit is cleared.
