**RESOLVED** How to know actual spindle angular movement

[Ashish B]

Hi

I think i previously posted remedies of problem & not the real problem.

I will try to describe my problem as under -

I have a application in which i orient spindle 2 times.
Firstly i orient it at 0 degrees. Secondly, i orient it at 30.3 degrees apart from 1st position.
I need to know/measure the actual rotation of spindle from first position.

I am sure that some parameter at servo drive receiver end must be tracing the actual spindle rotation.

But how to dig it out & do you have any idea that which parameter traces that actual rotation.

Thanks
Ash

Ashish,

You will have to search your spindle drive documentation for that information. If your spindle drive can output an encoder signal that meets our encoder specification, you could use the PLC to read the encoder and compare the two positions.

Please see here for our encoder requirements: http://www.ajaxcnc.com/ajaxbb/viewtopic.php?f=20&t=4
