Just taken a look at the machine again. Interesting observations. The DC motors all look identical, even for the 4th and 5th Axis but run smaller drives (assumably due to lower load). There is however no other feedback than Tacho. We couldnt find any linear / glass scales or any other form of feedba...

You can probably run that system with Oak (+OpticDirect) in analog velocity mode. The drives need the tachogenerator feedback from the motors, to do their speed control. The Oak needs quadrature position feedback to know where the axis is. No, there is no way to usefully generate a quadrature encod...

Hello, I've seen some DC motors with both tachogenerator feedback and encoder feedback. I see a lot of references to "measuring system" inputs on the controller and they sure look a lot like encoder inputs to me. The language in the manual suggests that they are linear encoders on the axe...

Also, just checked. Oak is only 4 Axis, correct? I need 5.

EDIT, watching a vid on the Oak board, there are additional Axis via the 'daughterboard'. Question about encoder feedback however will still remain. Thanks.

I believe you would be able to control these with an Oak in velocity mode. The wiring would probably be a little annoying since it looks like you'll have to wire the encoders directly to the Oak rather than to the drive. From reading the manual, I would try wiring like this for velocity mode: pin 1...

I'm assuming this is the inner working of the controller - not sure yet, so reviewing.

Ive looked at the programming manual, that doesnt cover the interfaces etc.

User manual for the drives attached.

Page 28/68 shows the inputs / outputs. The -10 and +10 Speed reference are what looks to be for tuning. The actual control is 9 and 10 and called 'Differential Analog Input'.
Thoughts please?

Thanks

Just checked, the drives are made by Control Techniques and seem to be plentiful, just trying to find a manual.
