The $FMSPDAT Function
result=$FMSPDAT(n,p)
Returns: Sequence
Virtual Machine Reference, Model Customization
Simulation Macro Functions, Virtual Machine Probe and Collision Test Functions
This function returns information about the p th interference pair of the n th collision/over-travel
event that occurred on the last motion. A sequence of length 7 is returned, as follows:
1 Event type. 1=over-travel, 2=collision, 3=measurement
2 ID number of the first component
3 Name of the first component
4 ID number of the second component (0 if over-travel event)
5 Name of the second component (blank if over-travel event)
6 Time at start of event
7 Time at end of event (same as start time for measurement event)
The $VMXFER(1) system variable contains the number of collision and/or over-travel events
that occurred on the last motion. This is the upper limit for n. The $FMSCEZ function can be
called to get the count of interference pairs for each collision/over-travel event. This is the upper
limit for p.
For example, to list all collisions:
DO/N=1,$VMXFER(1)
CEZ=$FMSCEZ(N)
DO/P=1,CEZ(3)
R=$FMSPDAT(N,P)
IF/R(1).EQ.2
ERROR/8,'Collision detected between !(*) and !(*)',R(3),R(5)
ENDOF/IF
ENDOF/DO
ENDOF/DO
The $FMSPPOS Function
result=$FMSPPOS( )
Returns: Sequence
This function returns the axes positions at the last point of probe contact for all moving axes. A
variable length sequence is returned, as follows:
1 Number of axes moved (0 if none)
2:4 ID number, name and position of the first axis at the touch point
5:7 ID, name and position of the second axis at the touch point
… …
To simplify processing, the $VMP* macro variables can also be used to obtain the XYZ linear
axes positions at the start and end (i.e., trigger point) of the probe motion.
