thanks everyone, nice manual jkh, and jk i did find a power supply on eBay for 225. one of the other cars has a power one power supply that was wired to the drive, so either way i will get it replaced and see the outcome. of course ill be on vacation for the next 10 days, so it will have to wait. Kone indicated that they have a upgrade for that drive, has anyone out there upgraded this drive

We only ever installed 1 Duplex on a Collage Campus. We lost the Contract to Schindler. I heard that they had a tough time with those units and replaced the whole Drive with something else.

well replaced the drive power supply with one i found on eBay, thanks jkh, this took care of the hard fault #9 and # 24, unit boots up with no errors now, the unit does run much smoother with the new power supply, however same problem in the up direction, car comes to floor commanded speed is 3fpm, car stalls and sets brake 3 seconds later, car off level. still works great in the down. did a complete msu setup, offsets etc, all went well as per the instructions, same outcome, still can't access drive, i have a level 3 tool, might need level 4 tool, going to have to look around. looks like they have a yaskawa drive upgrade that we could sell customer, going to look into that. will keep you posted

Looking back through some old material, I found a procedure for the drive velocity command calibration. I remember doing this on the two installs we had. Do you have a copy of this procedure? It perfectly describes your problem at the end of the procedure.

When the car stalls an 1" below the floor in the up dirrection and you have a floor command of 3fpm! Is DZU up?

Yes. Dzu is up. Hey jay i have some literature but if you could get me a few pages of what u have that would be great
I have not come across what you describe in any of my manuals

check your pm and advise.

update, car is running, I did the drive calibration, and still the same problem, i then adjusted the current loop balance per the instructions, by adjusting pots r92 and r94. they were both at .007 volts, adjusted to .000, and the car will now slow down in the up direction and set the brake normally, no hesitation as before. the only problem is that i could not get the up and down floor levels equal. the car would only stop level in the down direction, in the up direction, it would stop about a 1/2 inch low, if i adjusted the floor levels with the tool, i could get it to stop level in the up, but it would be 1/2 inch off in the down. i reset the vanes, and relearned floors again, but same outcome. so now I'm really confused. i was looking thru the drive parameters under msu motion adjust, and i noticed the parameter min_pos_error, it was set at .500 which is 5/10 or 1/2 inch. I changed it to .200 like the other cars, and now the car comes in nearly level in both directions. had to change it to .100 to get very nice floor levels. the car is still a bit slower in the up leveling as compared to the down, but it is running fairly nice.
actually this is the smoothest the car has ever ran. I'm sure if i could get into the drive, i could make some other adjustments to get the up and down level speeds more equal. but for now I'm just glad it is running, as i did not really want to install the new upgraded drive unit. i can tell the up speed is slower, as the doors are about 1/2 way open before the car finally stops level. in the down direction, the doors are just a little open before the car is level and the brake sets.

you should be able to access the Drive by plugging into the RS232 port at the bottom of the Main Control Board; then press F2 and enter the password. Sometimes you just have to say good enough as long as there are no safety issues. You may want to stop the Doors from Pre opening. That is a parameter in the Option Adjust Menu.

i know someone has logged into the drives, because the password for the drive is in all the controllers. drive password 0000 but when i plug into the port on the main control board, and press f2, i get the logon failed message thats it. i have a level 3 tool, do you think i would need a level 4 tool? i read that somewhere while researching that you may need a higher level tool. thanks for the help guys.
now on to the next adventure:}

I do believe your right, you may need a level 4 tool. These were rare birds. Both the Elevator and Level 4 Tools.

World Tool sells a Level 4 tool. It does all but LON.
