Does anyone have any experience with this drive? The elevator Is traveling up in the selected down direction.
Motor is a 31HP (Ac/Dc) Loher Motor, 5 Lead.
Has PM, UM, DM Contactors
In the up direction PM and UM pick as advertised runs up
In the down direction PM and DM pick but elevator travels UP.
- Runs on inspection up no problem.
- Put elevator at mid point - Not drifting up
- Down selected on inspection. Elevator runs in the up direction for 7-10 seconds, causes the drive to fault out.
- Sent drive out to see if there was any issues.
Drive installed and problem persist.
- Swapped L1 and L3 still travels up when down selected up.
- MCE says they dont know.
- GAL offered some Tech support on the Drive and they don't know
