Hello, friends!

So we got this Kone MX20 PMSM flat motor removed, rewound, re-installed, set the resolver angle, polarity, tach polarity, did a shaft learn, adon learn, and this thing now runs on automatic, to all floors! Hooray! Thanks to all of you, my friends!

Only thing is this, when it comes to a floor, it levels in normally, then it comes to an accurate stop normally, then the c/o doors open up. All good so far. When the doors are about 3/4 the way open, you can hear the main brake set- "clunk". (Is that a selling point?) Anyway, very typical, and all good so far.

But, after the main brake sets with that characteristic "clunk", the then car drifts up about 1/2". which is about 12 mm. No bueno. It stops, but only after it has drifted up. It must stay at floor level, after the brake sets.

We are re-adjusting the brake shoes, looking for .004", which is roughly 0.1 mm.

We are checking the loadweighing.

Any other ideas?

Thanks in advance!
