I have retro fit a milling machine with Argo drivers (runs 130v DC Servos), I am using the original PSU 2kw transformer, rectified to 110VDC. machine is mostly working other than what I would describe as a bouncing when the axis moves. It seems reach the position then reverse direction then go back to the correct position.
Here is a video of the fault:
I assume this is due to incorrect tuning of the drive, I have messed about with the KVP & KVI settings as per the wiki found here: https://granitedevices.com/wiki/Tuning_position_controller
This is the output from the scope:
Messing with the KVP & KVI setting seemed to only allow me to drop the blue line from more of an angle to the flat as illustrated here:
But I am do not seem to be able to manipulate the blue line as shown here:
Any help would be appreciated.
