Got car that’s stops in flight according to customer
Never see it happen
Dsd512 drive
24 floor building
Only faults are possible drv/1028 error, drive fault,speed fault ,stop switch fault
Checked in car stop switch ok
Swapped processor board and drive board
Jumped car stop switch
The drive fault is 118 communication fault
Swapped cable for drive to processor
Car is still intermittently stopping in flight with these same faults all different areas in hoistway
Any idea what I might be overlooking?
