High-Speed Capture VIs
High-speed capture inputs are an enhancement to the encoder FPGA and are available when the encoders are operating as axis feedback or as independent encoder resources. High-speed capture functionality is available on servo and closed-loop stepper axes.
You can use High-Speed Capture VIs to configure, enable, and read the status of high-speed inputs. Buffered high-speed capture is also available on the NI-7350 motion controllers. Buffered capture is a more advanced use of high-speed capture where the captured positions are stored in a previously-configured buffer. This helps the high-speed capture perform at higher capture frequencies. Refer to the Buffered Operations Overview for details on buffer operations in buffered high-speed capture for the 7350 controller.
The high-speed capture inputs also can function as latching general-purpose inputs. Configure the inputs as you would for high-speed capture operation, but ignore the captured position. You can then read the state of the latched inputs.
