54 Operation Theory
ond command to the executing register and the third command to
first buffer. Now, the second buffer is empty and user can set the
4th command into 2nd buffer. Normally, if users have enough time
to set a new command into 2nd buffer before executing register is
finished, the motion can run endlessly. The following diagram
shows this architechture of continuous motion.
Besides position command, the speed command should be set
correctly to perform a speed continuous profile. For the following
example, there are three motion command of this continuous
motion. The second one has high speed than the others. The
interconnection of speed between these three motion functions
should be set as the following diagram:
If the 2nd command’s speed value is lower than the others, the
settings would be like as following diagram:
