SSI absolute encoders and analog servos

Hi,

Yes machine has been in use for few months now. Works 100% ok.

Would you mind sharing config files, as it would save me a lot of time, and i am badly pressed for time ( it is 3:01AM here). I already have the hal and ini you shared here, but that uses simulated stuff, i just need the SSI part for reading and feedback. Never used them, but i learned a lot from this thread and other resources, so thank you very much for sharing.
Tomorrow (well today already ) i am connecting one encoder and see what happens.
I have a similar setup to yours, namely 6i25/7i77/7i74/7i70/7i71 and a revolving tool changer, and two X axis, one 6450mm long and one 400mm.
Plenty of fun!
Regards,
Tom

Those are shared on page 10 of this thread....

Thank you, i already have them so i will give it a try today.

Unlike quadrature encoders, SSI encoders need a lot of encoder specific setup
so you need to get a number of things right for the SSI encoders to work:

1. Clock polarity
2. Data polarity
3. Number of bits
4. Gray code or binary data encoding
5. Extra pad or fault bits

Basically this means you need the encoder data sheet or you will be working in the dark

Could not find anything about them except the wiring diagrams i have, nothing pertaining to usable info about encoders.
Terkaa, just checked the hal and ini files, they use core_sim4.hal, so it does not use actual hardware, when i remove that line, it does not start complaining about invalid icon size 48.
