Hello everyone,
I am currently setting up my plasma cutter and encountering some initial issues that need resolution. One of these issues is the intermittent loss of my THC encoder signal, which occurs briefly at irregular intervals. Aside from this, the signal quality appears to be satisfactory in terms of noise. When the signal is lost for a few milliseconds, the torch attempts to compensate by raising itself before leveling again. I have attached a photograph (apologies for the quality) that illustrates the signal drop, followed by a voltage increase caused by the raised torch before it levels again.
I am utilizing a Beckhoff EL5101 incremental encoder interface in conjunction with a Mesa THCAD2. I have also tested with a THCAD300 I had available, and the issue persists. Additionally, I am employing hypersensing with a second THCAD2 and another Beckhoff EL5101, exhibiting the same behavior. Given that I previously used the THCAD300 with a 7i76e without issues, I suspect that the Beckhoff modules might be the cause.
Attached are three screenshots: one showing arc voltage at 0V, another displaying encoder frequency initially at 0V and then at 12V for testing purposes, and finally, the problematic screenshot showing encoder frequency during cutting. What options do I have to filter these signal drops effectively?
Thank you in advance for any advice or recommendations.
