CAPTURE Features

Set P5-39.X0 to 1 so as to activate CAPTURE function and
this DO is OFF.
Note 
If P5-38=0, set the value of P5-39 X, Bit0 to 1 will disable the
CAPTURE function. Clear the setting value of P5-39 X, Bit0
to 0 and set DO.CAP_OK to OFF.

Since the capture axis is 32-bit wide, the accumulation will
cause overflow. Please avoid this.
The CAP data is saved in data array and the first CAP data locates in P5-36. The CAP
number has no limit, thus it can be set via P5-38. The last CAP data is saved in P5-36

1. Set the value of P5-39 X, Bit0 to 1 so as to activate CAP function. Every
time when DI5 is triggered, one data will be captured and saved in data array. Then, the
value of P5-38 will decrease one automatically until the CAP number reaches the
setting value (P5-38 = 0). The CAP procedure is completed, the setting value of P5-39 X,
Bit0 will be cleared to 0 and DO.CAP_OK is ON.
When capturing the first data, the position of CAP axis can be reset. The first CAP value
will be the value set by P5-76. And the value of the second CAP data will be the
incremental value from the first data. This method is called Relative Capture. If not
selecting the first data reset, it is called Absolute Capture.
When capturing the first data, it automatically activates COMPARE function, which
means the COMPARE function is activated via DI5.
