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.
