PaulK Posted October 26, 2017 Report Share Posted October 26, 2017 Hello, I have inherited this problem that has been plaguing this system for 4 months. The customer wants us to swap out for AB or Siemens, but I think this should be correctable. I have the following hardware... V200-18-EB6 EXL-CAB295 EX-D16A3-R08 These black screens only appear 1-20 minutes after a 3 HP VFD and pump starts up. We have ferrite coils on the 24 VDC going to the V570. Everything I have been told points to noise. Where should I start? Zener Diodes? Quote Link to comment Share on other sites More sharing options...
