Once again have this Miprom giving me heck.

13 stop, 10,000lb capacity, 2:1 basement machine, HPV900

Have Kone Service Tool intergrated into a computer purchased from Kone Spares.

Background of elevator
*had issue with MSU board giving only positive DC command to drive(was fixed and ran fine)
*the issue listed below started happening(changed CPU, MSU, Relay Pilot Board, did not change)
*found bad traveling cable(replaced both, as they each had their own separate issues. ) Did not fix issue.
*Replaced cartop encoder during the traveling cable change out.


Symptoms
*from 9th landing down, while on inspection, will run for approximately 2 seconds then shut down, waits 5 seconds for reset then will run another 2 seconds. Up and down direction.

*around the 9th landing, car will start running a touch longer, then right about 10, will run nonstop as it should in up or down direction

*10th landing is a little over halfway of the entire rise.

*No faults are listed under motion excuses.

*No faults show on the drive(No overvolt, torque limit reached, etc)

*If I pull the cartop encoder off the rail, elevator will run at bottom of the hoistway without stopping every 2 seconds.



Service took does not allow me to adjust drive, as it is a magnatech and not a Baldour. Any help would be greatly appreciated.
