Hi,
I have an application where I need to determine the frequency of a pulse train coming from an inductive prox sensing gaps in the structure of a flywheel. I'm estimating it to be somewhere between 60hz to 100hz when it is at speed. This is not critical to the process so much as a crude protection for the reversing motor starter and indication we are at at least 90% of flywheel speed to enable full power stroking. Normally I'd have a press control and could just use an output from that but this is a hot-work forging application where OSHA doesn't require a safe press control.
I have a prox with a 300hz switching speed running into a 1734-IB/8 PointI/O card. Is this possible given the hardware I have?
I've looked around the net for some sample code to get me started but my Google-Fu is coming up short here.
Any ideas?
Jim
