Hello,
When you perform Buffered Position Measurement, I/O connections are as described below:
* Connect the encoder A signal to the source pin of the selected counter (SOURCE)
* Connect the encoder B signal to the aux line pin of the selected counter (UP/DOWN)
* If you are using Z indexing, then connect the encoder Z signal to the gate pin of the selected counter (GATE)
* Connect the data latching signal to the selected gate input of the counter (PFI or RTSI)
There is a difference between the selected gate of the counter and the gate pin of the counter.
The gate pin is a specific hardwired pin of the counter.
The selected gate of the counter is selected using Counter Set Attribute.vi.
You can use the "Measure Buffered Position (NI-TI
O).vi" in the Example Finder of LabVIEW to perform a test with Z-indexing from a quadrature encoder.
I hope this will help.
Regards.
