somebody knows how the micrologix 1500 can to show rpms, if you have a ladder a apreciate very much, tank you

Micro,
what frequency do you want to count? (rpm)

(8{)} ( .) · Jul 22, 2009

Lancer's question is a good one.

There are several ways to do this. The most common are probably:

* Tachometer
* Count pulses per time period and calculate to RPM
* Count time between pulses (assume 1 pulse per rotation) and calculate.

Let us know which method you want to use and we'll get you going.

I have a 1000 pulses per revolution encoder, and the rpms maybe 200, but I want to know how is the configuration of the micro for speed monitor and not for counter.

thanks

Use both the HSC and STI function files. The STI will execute on a periodic rate that you determine. Calculate the RPM in the STI based on the change in counts since it was last executed.

sti module

How do I get the measure of sti?

I do the following
sts start the sti
PFN = Number of ladder of hsc
UIE = 1
AS = 1
SPM = Amount of time to interrupt the hsc
thank you

I want to thank everyone, but my pc suffered severe damage and had to get a new one to do these tests.
I urge apology pc

There is a good technote on this exact application in the Rockwell Automation Knowledgebase.

I can not access this site because I need to call ab. if you can appreciate the information you enter to salcedorigoberto @ hot

The RA Knowledgebase is just one of the things you get when you have a TechConnect contract; the phone support and software updates are probably the most crucial. Oh, well.

There is a related thread on a related forum that might help you.
