HI, I have a project with a CU240E-2 PN-F and PM240-2 IP20 that has r2 = 44 switch on inhibited-supply STO terminal w/24V (hardware). I have no idea why it's throwing this error! STO is not active in this project.

I attached the project I downloaded to the VFD. It threw this error after I swapped the CU between two panels to debug a different issue. Swapping the CUs back didn't help.

I appreciate any insight!

I measured 24V in these pins and 0V as noted.
