Teach (Record and Play-Back)

Several applications require teaching the machine a motion trajectory. Teaching can be accomplished using the DMC-1700/1800 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-1740 or DMC-1840)

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
