Summary: replaced a PF700 that showed speed and voltage in torque modewe replaced a old PF700 that went bad. upgraded with a PF753. we no longer can see speed feedback in rpms or hz or voltage output in torque mode. this application is used as a nip roll in a paper machine wet end. we see it running, showing 30 amps output. it shows -0.75 hz with the arrow negative on the HIM. it has a pot for torque reference . it has a positive torque reference. machine seems ok but just wondering. the PF700 used to show speed and voltage output. Is it ok or do we still have a problem. we used to run at 78% torque reference but now only at 28%. if we turn up the torque pot to what we ran at before it trips on overload. [/INST] here is a drive observer picture what we see, estimated rpm about 1400 \\n </s>
