smartrise traction fault A152 over/undershot

hi guys cant find this error in the manual it stops at A148 keep finding the car low in the basement with this error, reset and it will run for a week andcome back.

My manual only goes to A148 also. Better call Smartrise in the morning. The debug menu should have some history and a description of all of the faults and alarms that it has logged.

If I were to take a guess I would check for worn selector tape guides. If the guides are worn the hole count could be off and overshoot a floor, perhaps.

infritzwetrust is right, check tape guides.
Also, do you have A60 error on fault log before A152?
If so go to adjust parameters 13-097 from x00 to x04
Re-learn the shaftway.
If car overshoot floors, depend of the contract speed check your slowdown settings is it correct.

Thanks guys. Will go to the guides next. Stay safe

Hey guys. They sent another mechanic to Job to replace guides at last shutdown. There was the F71 speed dev error with the A60 position error. Will see if the guides help Thanks again you guys are great. Love this forum
