hey guys I'm having a bit of an issue with up stopping on a kone 516 traffic master. 2 speed motor with a scr drive that consists of a couple of circuit boards and 40 firing boards. in the down direction it is levelling into the floors great but in the up it seems like it lags in the slowdown then drifts through the floor and levels down. ive changed and verified the up levelling switches as well as the door zones. ive replaced a lot of relays that have to do with the up direction. unfortunately I only have one of these units of this model so I cant even compare. any help would be great. work hard and work safe.

These are getting rarer than hens teeth
You may need to get the old silly scope out and a test card for drive

once set up they run great but can be right pain in the ass when they don't behave
