Working on a servo motor here for an in-house project and have noise issues when dealing with mV signals for the load cell on the same system. What are your preferred EMI filters for the drive side?
The project is still on the work bench currently and I know the noise issue will get reduced with better grounding and shielding for components, but it won't fix it entirely from other equipment we've done.
The drive/motor is an import 240v single phase 4kw unit, so it isn't anything large. The signal cable for the cell is shielded cable, but is is conducted EMI through the equipment, with it connected the values float +/-25lbs with the drive energized and without it powered it is +/-1.
Do you have any preferred source for drive EMI filters on servo motors or even the same for VFD drives? I can find stuff online but everything is a call for quote and before I go down the path of calling multiple people thought I'd ask here.
