The actual car speed (measured by the governor or encoder) exceeds the commanded speed from the VFD by more than 15% for more than 100 milliseconds.
Top tier – Most Common Nuisance Fault
When an error condition is active, the top line of the display constantly alternates between the raw error code and the subsystem status flag. During troubleshooting, technicians can toggle the menus to read live metrics, such as real-time travel speed and traction media counter values. schindler 5500 error codes top
Use a multimeter to verify the auxiliary continuity state shifts cleanly when manually pressing the contactor armature. ShaftChecksum / PosLost_KSE
Always prioritize passenger safety. If the error code indicates "Overspeed" or "Unintended Car Movement," do not attempt a reset remotely. Physically inspect the car first. The actual car speed (measured by the governor
The car arrived at a floor, but the door lock signal was not confirmed within the time limit (usually 5–8 seconds).

If you are currently facing a specific code on your display, let me know the or describing the current car behavior (e.g., doors cycling, car stuck at a terminal floor). I can provide the exact sensor location or matching schematic reference point. Share public link
Errors related to the steel belt monitoring system, often resolved by verifying and updating date/time parameters in the system. Drive and Inverter Errors (Drive System) These codes relate to the motor and frequency converter: 0430 / 0431: Brake switches do not match the commanded state. 0435 / 0436: Motor overtemperature or recovery.
