Ok but you could still try the invert option to see, only a click in a box.

I only use the encoder outputs from my servo drive, I only have the motors encoder. What I do is have the outputs from drive go to IP-A then have them jumpered across to the Enc module, seems to work fine for everything except the Spindle Align. I am wondering if it has something to do with the drives outputs as my actual encoder is sine/cosine so doesnt have an index pulse as such.

I did that too, jumpered A B I , but from spindle pulley encoder to both IP-A and ENC.  Didn't help the PID issue. Don't have an explanation why they want motor encoder. Never connected the spindle enable in plugin cause between brains and macros, it's already a puzzle. I should write something up as a heads up with brains and macros commingling.

I think what they are meaning is normally you will have 2 encoders unless the motor is direct drive as in my case. So that way I can use the encoder for both.
As said however my actual encoder is not suitable as it is sine/cosine but as my servo drive can be set to send out interpolated encoder signals rather than just passing them out it works fine.
Although the Orient isn't working. Whether that is the drives output or the IP-A that is at fault I am not sure. I suspect it may be the drive as I looked at the drive in its software and I never saw the Index pulse change, it was constantly on. That stands to reason as there is no index pulse on the encoder with it being a Sine/Cosine encoder, I however thought the drive would manufacture one, maybe it is not correct, I will have to haul out the scope one day and see.

Main thing is you have it working by other means.

Hello LM941,

did you ever get the spindle orientation running ?
i am in the same Situation now.

Thank You Thomas.
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

I'm retrofitting: Sugino Self-center V8
Original computer: CNC-300G made by Horyu Engineering
Drives: Horyu Engineering
Motors: Sanyo Denki BL Super, those motors are equipped with absolute encoders (probably)
Encoders are connected directly to the drives. Those drives have encoder outputs A/B/I for the CNC control.
The spindle has only one encoder, i did connect it to the A-axis input and bridged it to the CSMIO-ENC first encoder input.
Firstly I had the -ENC module disconnected and the spindle configured in open loop, checked and adjusted the V/rpm curve.
Then I changed the configuration to "Enable spindle axis" and adjusted the closed loop PID.
Meanwhile I had to find out how many pulses per one rev I have.
Then I connected the -ENC module and activated the Align at stop function.
After M3/4 Sxx command M5 causes spindle to stop at that given angle.
You need to have an encoder with "I" signal one time per one rev.

If any more info (screenshots, etc) are needed please let me know.

is your spindle step/dir driven or 0-10V?

Hi all,

I am at this same point practically = i want to add a 4th axis to my mill, it will be driven at 1:1 with a servo motor.

CSL are pretty adamant i must have two encoders - one on the motor and one on the spindle, if i'm at 1:1 ratio this seems pointless.

Having read this thread, my thoughts regarding paralleling the drive encoder outputs between IP/A and ENC modules seem to indicate that it will actually work ok??

ope i read that right as fitting another encoder will be difficult. I would have thought CSL could have put a tick-box in the setup so that "Use motor encoder if at 1:1 ratio" could be achieved internally.

I have asked them several times why not and they seem unwilling to answer.
