General Mach Discussion / Dither
« on: August 10, 2012, 03:35:24 PM »
We get a lot of dither with an analog servo drive system using Mach 3. When the system is idle, the DRO for the axis will dither by a few hundreds of a millimetre. The output voltage to the drive is low, but present. Is there any way to eliminate the dither. It is like the PID is oscillating slightly. Thanks.
