CAPTUREINTERVAL/CPI
Purpose:
To define the interval of the data capture in relation to the servo frequency.
Controllers Supported:
NextMove PCI NextMove PC NextMove BX MintDrive ServoNode 51

Description:
The keyword
CAPTUREINTERVAL is used to specify the interval of data capture reads in units of servo
loop ticks. This does not apply to high speed capture on ServoNode 51.
Example:
LOOPTIME = 1000
CAPTUREINTERVAL = 4
CAPTUREAXIS.0 = 0
CAPTUREMODE.0 = 1
CAPTURE = 1
The above example will capture the measured speed from axis 0, every 4
th
iteration through the servo
loop (i.e. every 4 ms).

Description:
The keyword
CAPTUREMODE can be used to either assign a capture mode for a capture channel or to
read the mode currently assigned to the capture channel.
The valid modes of capture are as follows:
