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!

my guru says your main brake isnt setting right, says .003 when picked. says you need to be able to spin the washers on the main brake when set.
says to check e brake set time and change to 3.0 seconds, thats your delay when doors open. says default is like 30 seconds.
lemme know if this helps, if not, provide more detailed info, and we will get it nailed down. Thank you very much! Going out there tomorrow, will check on that stuff. Wow, .003, really? I can say almost for certainty that it is not set that close now. Maybe a wide .004". But we will set it to .003".

the clunking will get better after you adjust the pod --lol brake pod to .004 -do you have the brake tool No, what's that for? (probably for adjusting the brake, duh!) We were swapping main brake for emer brake power supplies in the controller. Then go back to the car top, push the car top inspection button, which picks the emer brake. but when you swap the wires main for emergency, it don't know which brake it's picking, that way you can adjust each brake one at a time. Then put them back right when you are done. Maybe a bit slower than the portable brake power supply, but at least you can pick each brake. Is that what you mean, by "brake tool", the portable power supply?

I've been remiss to update you, my esteemed colleagues!
Sh#t, I've been so busy, sorry..
If I am on the car (245#), it stops accurately at all three floors, up and down.
But if I get off the car, it will stop just fine to all floors up+dn, EXCEPT the top floor. Going to the top empty, it comes in very controlled, stops, then as the main brake is setting, it rolls up a bit, trys to level down, 61u+61n high), sets the brake, rolls up, etc, etc, then after a number of tries it faults out. I suspect it only does this at the top floor, because all the host ropes are hanging down the cwt side.
We got both brakes pretty close, about 003", but Monday I'm gonna do them again.
Is there a timer that holds anti-rollback torque until the brake has well and fully set? I was so busy Friday, I didn't check loadweighing, but will Monday
Thanks everybody

ifrratedpilot- We have been spinning the washers, making sure the mechanical brake release linkage is having no effect on the brake when it is set. We went so far as to take the actuating arms off the brake entirely, (washers spinning freely)just to completely rule that out!
While the eBrake set time should be low, to prevent heating of the ebrake coil/armature, it cannot be a substitute for the main brake not setting properly, or a problem with load weighing, resolver angle, etc. But yes, we lowered the eBrake set time to 3 seconds. IIRC, that is the lowest time that can be set with that parameter, so it would not help to catch the car on the initial stop. Therefore, the eBrake cannot remedy this issue, right?
The car is rolling upward, during main brake set. By the time the brake "catches" the car, it has rolled upward far enough for 61U to go dark, initiating down re-level. (I still like to think of it as old-school "LD" going high!)
I'm not sure what other people mean when they say the terms "rollback" and "rollforward", but this car "ROLLS UP", before the main brake catches the car. When I was at Otis, we called this "rollback".
theshaft, We will check your suggestions tomorrow,
Thank you everyone very much for your input, it is sincerely appreciated.

Thank you everyone very much for your input, it is sincerely appreciated. i'll put another call in to my Kone Guru, see what he says...
Nothing to prove anymore, done it all.
