Em...
I did mean when the servo is in-position, ie stopped.
At that point there is no dither.
Of course, if you try to move it off-position, it then activates and tries to get back into position.
I think all manufacturers make servo drives in to multiple kW or more.
Mine is 2.5 kW continuous.
Much bigger ones are available for not much more money.
30 Nm peak, 10 Nm cont.
Belt drive at 1:3, with HTD8 profile belts, 30 mm wide, taperlock pulleys.
So 90 Nm at the spindle.
The motor mount is a frame, from 30x40mm tool steel bars, and the motor is hard mounted to a steel plate 2 cm thick.
Motor is on top of HS, so heat does not distort spindle (grow it).
I use step/dir with a csmio-ip-s controller
+, enc, mpg, extra io addons
