text: <s>[INST] Powerflex70 0-10Vdc input funky I have a powerflex70 on a chiller controlling condenser fan motors. I measured the 10Vdc signal on my input terminal. But when I read what the VFD is reading with parameter 17, it's flickering between -5Vdc to 4Vdc. Installed new shielded wire between my controller output and the VFD but with the same results. See the video here: https://imgur.com/gallery/hT2VvS5 [/INST] Is the shield on your new cable grounded at the VFD end? Is this new cable run near AC cables (such as VFD line in or motor cables)? When you say you've measured the analog signal at your input terminals, could you be more specific? Are you saying you measured the signal at the VFD analog input terminals and the signal did not flicker on your multimeter? Using a multimeter to read the signal: have you lifted both conductors from the VFD terminals and measured it? What provides the analog input signal? A potentiometer? An analog output from a PLC? \\n </s>
