That tolerance is specified in your ini file - what values do you have? Seb has acknowledged that there are issues and is working on it. Further speculation, especially without hard data, is pointless. If you are curious about what is going on, break out halscope and take a look. The command, the feedback, the error, and the error limits are all available as HAL pins or parameters, and there is also a "faulted" parameter that can be used to trigger the scope.
