Hi sirs
I have CAM TECH Gantry tipe router and right now I changed step motors on DMM servo 750W motors and DYN3 AC servio drives X have 2 motors
I use 65000HZ kernel speed and supplied DMM DMB4250 Breackuot board
Motors X and Y I machanically connected trough belt and gears ratio 1:5 Z trough gear ratio 1:1 lead screw pitch 5mm
Every thing work fine but I have issue
Random and unpredictable axis moving and drivers giving  fault in enable1 signal
I connected all drives  controll circuit trough one power filter
Every drives power terminals connected separate phase
I checked many times all connection and everything fine but issue same
All help will be fine
Thank you
