I know that its possible to implement an analog axis for softmotion using encoder-feedback, and analog setpoint running over an industrial bus.
This however gives a terrible response due to the latency of feedback to setpoint, so I am wondering if anyone know of a module that closes the loop in a single IO-node?
Ie. it does the P/I/D/V_FF position-loop calculation for a standard +/-10V with encoderfeedback, and is mappable as for instance a Cia402 or Ethercat-axis in CoDeSys.

It seems an obvious product, that would allow softmotion to be used with large drives, hydraulics, stepper-drives, retrofitting to older machines etc.
Its essentially implmented in every-drive for softmotion out there, except as a standalone part....
So there is a market for this, I just cant find any relevant products.

Anyone know of such a product?
