How to read Encoder Index through Pxi 7358 Motion Controller?

[Jags]

I have  a rotary quadrature encoder connected to an actuator output.

The encoder is hooked to Pxi 7358 Motion Controller thru UMI Board 7774.

My application involves the measurement of speed fluctuations at the actuator output using the encoder position data. Though i am able to capture the encoder data, I would like to find out how to start (and stop) the capture based on the Index signal from the same encoder.

Can someone guide me on this?

Thanks

Jags,

the 7358 doesn't provide trigger capabilities for position measurements. If you are looking for advanced measurement features like this I would recommend the usage of a PXI-6602 or of an M-Series board (e. g. PXI-6220).

Thanks for the info, Jochen.
