But as I said if I calculated things correctly then the max line count you could use is 1000 (4000 pulses per rev)

@ Hood,

That become an expensive encoder USA shipping + tax
but ok if it will work


1- Can that be so directly linked to the ENC or should there be some extra geprogammeerd?

2- That 5V supply is that of the ENC or is that a separate power supply?

Just a thought but only the index signal needs to be one per rev for the thread start point The Controller would have no idea that the encoder was geared to the spindle as only the count per rev would change with gearing.

10,000 /2 = 5000 rpm at the encoder.

Add a seperate indexer signal on the spindle. One per rev.

Dear,

Must work with ENC http://www.cs-lab.eu/en/produkt-11,2-CSMIOENC_threading_module.html

and / encoder 10K rpm

of cs lab 6K rpm see linkhttp://www.cs-lab.eu/en/produkt-19,4-Incremental_rotary_encoder___differential_signal_TTL_5V__2500_prev__IHU4808.html

You can always send me a concrete wiring diagram

grtz

Ideally you also want a line driver. US digital sells them or you could make your own circuit up.

You would use the 5V and 0V connections on the Enc module to power the encoder.

@Hood Link you can send those line driver

thx

Also should have said, the Enc module itself will not be an issue, the spindle on my Chiron has a max rpm of 3800 and I have an encoder output of 32,768 pulses per rev, so that is  just over 2MHz.
With a 2500 line encoder at 10,000 rpm that would be 1.6MHz.
I think the Enc module can handle at least 3MHz.

Hood
Hi, you say ENC module can handle at least 3MHz.
Can't seem to find this information. How do you know this?
Grtz.

Wojtek said in response to a question I had, well actually just looked back my emails and it was with regards the Encoder inputs of the IP-A. I would presume however that the Enc module would be the same.
Here is what Wojtek said

Max. encoder input frequency for CSMIO/IP is 3Mhz.
