Teach (Record and Play-Back)

Several applications require teaching the machine a motion trajectory. Teaching can be accomplished using the DMC-13X8 automatic array capture feature to capture position data. The captured data may then be played back in the contour mode. The following array commands are used:

DM C[n]	Dimension array
RA C[]	Specify array for automatic record (up to 4 for DMC-13X8)
RD _TPX	Specify data for capturing (such as _TPX or _TPZ)
RC n,m	Specify capture time interval where n is 2n msec, m is number of records to be
	captured
RC? or _RC	Returns a 1 if recording

Record and Playback Example:

#RECORD	Begin Program
DM XPOS[501]	Dimension array with 501 elements
RA XPOS[]	Specify automatic record
RD _TPX	Specify X position to be captured
MOX	Turn X motor off
RC2	Begin recording; 4 msec interval
#A;JP#A,_RC=1	Continue until done recording
#COMPUTE	Compute DX
DM DX[500]	Dimension Array for DX
C=0	Initialize counter
#L	Label
