Max Velocity
Cam.#.Vel
This parameter is the maximum velocity of the Timed Base Index.
Number
Capture.Number
This parameter defines the size of the Capture list.
Capture Activate
Capture.#.CaptureActivate
If the Capture component is enabled and has been reset (CaptureTriggered is inactive), then the rising edge of CaptureActivate will
capture the four data parameters and cause CaptureTriggered to be activated. If the Capture component is not enabled, or has not
been reset, the CaptureActivate will be ignored.
Capture Clear
Capture.#.CaptureClear
This command may be used within a program to rearm the capture for the next cycle. This command can be used instead of
Capture.#.Reset destination which needs to be cleared after a control loop cycle to allow another reset.
Capture Enable
Capture.#.CaptureEnable
The CaptureEnable is used to enable or "arm" the capture component. If the CaptureEnable is not active, then the CaptureActivate
has no effect, and the CaptureTriggered remains inactive. Once the CaptureEnable is activated, the Capture component is ready
and waiting for a CaptureActivate signal to capture data. CaptureEnable is a read-only destination on the Assignments view, and is
accessible through a user program.
Capture Reset
Capture.#.CaptureReset
The CaptureReset is used to reset or re-arm the capture component after it has been activated. If the capture has been activated,
the CaptureTriggered destination will be active. The capture component cannot capture data again until it has been reset. The
capture component will automatically reset itself if the CaptureEnable signal is removed.
Capture Triggered
Capture.#.CaptureTriggered
The CaptureTriggered signal is read-only and indicates that the Capture component was activated and that data has been captured.
CaptureTriggered will activate on the leading edge of CaptureActivate if the Capture component is enabled and reset. Capture
Triggered will remain active until CaptureReset is activated.
Name
Capture.Name
You can assign a descriptive name to each capture, making the setup easier to follow. The length of the text string is limited by the
column width with a maximum of 12 characters. Simply double click on the Name field of any capture's line to assign a name to it.
Number
Capture.Number
This parameter defines the size of the Capture list.
Captured Master Position Homed
Capture.#.CapturedMasterPosHomed
On the rising edge of the Capture Activate event, the master axis position is captured (in counts). The captured counts value is then
converted into Master Distance User Units and stored in the Captured Master Position parameter. If the user redefines the zero
position of the master axis, the master position in User Units is zeroed out, however the counts parameter is not. Therefore, if
another capture occurs after the position has been zeroed, the value stored in the Captured Master Position parameter will be off by
the value of the master axis before the position was zeroed out. This parameter is to be used if the master axis position is redefined
after power-up.
