Hey folks! Just defined this motor based on the data sheet provided by DFH.

When I enable this it produces a very audible whine while holding, something that is not present without autotune enabled for this one motor. This is the only motor that this is happening on. The other 7 motors between my Trident and ERCF v2 I have it defined on do not experience this.

Did I do something wrong defining the motor? Is there something else I am missing? Any help is appreciated, thank you!
