Download the r990H PDF files and just follow it, start with KP
increasing it till the motors starts to vibrate back and forth,than
increase KD to damp the vibration till the motor stand still.
I find out that KI is just to adjust how much the motor over shoots
the position and than moves it back to ajust the position, generally
I leave it full ccw.
You'll need to make a cable as by rutex instructions to connect the
parallel port to the drives, and run the tunning software, here I see
only one information that's helpfull, you can see how much the drives
overshoots before stops, and a curve that shows that.
If your motors runs out of controll, just reverse the motor power
supply wires, or the encoder A-B inputs.
holpe it helps.
