Pfaff 545 Thread Tension - Changes in reverse mode

[baileyuph]

The Pfaff 545 thread tension is acceptable for forward motion through put .........but notices the
tension changes a bit (noticeable) when using reverse.

It is the only machine in my group doing it - the Pfaff 1245 tension doesn't change during a shift
in sewing?

I minimized this issue on the 545 by tightening the upper thread tension, but still have a difference.

Why would the tension change in reverse?
