Chapter 7 Motion Control ASDA-A2R Series
Revision December, 2014 7-37
The value of COMPARE is saved in data array and the first compare data locates in
P5-56. The CMP number has no limit, thus it can be set via P5-58. The last CMP data is
saved in P5-56
＋P5-58－1. Set the value of P5-59 X, Bit0 to 1 so as to activate CMP
function and start to compare the first data of data array. Every time when a position
saved in data array is compared, the compare DO will be outputted. Then, the value of
P5-58 will decrease one automatically and compare the next value until the CMP
number reaches the setting value (P5-58 = 0). When the CMP procedure is completed,
the setting value of P5-59 X, Bit0 will be cleared to 0.
When comparing to the last point, it can select if it returns to the first data for comparing.
This is called cycle mode. Or it can activate CAPTURE function and wait DI7for
triggering CAP/CMP procedure.
