Sample Application Programs

Chapter 10

1012

Important: Note that:

due to the specified acceleration and deceleration rate of move #14, the axis

will not achieve the final velocity rate of 5 in/s

because moves #16 and #17 have discrete input triggers which may be

triggered at any time during their movements profiles, the axis may not

achieve the final velocity rates of 2 in/s and 3 in/s

all motion segments and programmable I/O information could be contained

in a single motion block. Three motion blocks are used here to demonstrate

the recommended method of loading multiple motion blocks into a module.

Planning the Data Blocks for Application Program #2

For application program 2 a PLC-5/15 processor is assumed and the data blocks

are assigned as shown in Table 10.C. The files used are shown in Table 10.D.

The data table for the parameter block for application program 2 is the same as

shown in Figure 10.4, for application program 1.
