Drive errors usually point to the regenerative drive system, inverter modules, or the permanent magnet motor.
| Error ID | Name | Description & Primary Causes | | :------- | :----------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | Inv Car Pos | Invalid Car Position. The actual car position read from the encoder is not within the learned floor range (more than 1 meter above or below the highest/lowest learned stop). Causes: The car position encoder was moved while power was off or disconnected (Action: Perform a learn trip). A faulty encoder (Action: Replace encoder and perform a learn trip). | | 1502 | Position Jump | Excessive Position Change. The software calculated a change in car position of over 240mm between two consecutive readings (every 10ms). After 5 consecutive cycles, the system logs the error, performs an emergency stop, and blocks the elevator. Causes: Electromagnetic interference (EMI) issues with the car position encoder. A faulty or incorrectly wired car position encoder. | | 1505 | Inv Fl Pos Trp | Invalid Floor Position during Trip. The error description indicates an inconsistency in floor positioning during a trip. The error forces the controller into a persistent blocking state that requires a manual reset to clear, emphasizing the system's high safety standards. Cause: The elevator is reporting a floor position that is inconsistent with the learned data for the hoistway. | | 92 | I/O Monitoring Fault | Abnormal I/O Status. The travel control monitoring system has detected an abnormal status of I/Os on the inspection panel circuit, typically for REC or RH panels. Cause: Unexpected activation of relays (feedback contact), faulty overbridgings, or bad input statuses. This error blocks the control persistently and requires a manual reset. | | 99 | General Fault (Contextual) | A non-specific error often seen on the SMLCD display. It is frequently reported in conjunction with other faults, often appearing after an overshoot and reset attempts. Like error #135, it can contribute to a persistent blocking state. |

Errors associated with safety circuit ruptures or overspeed tripping require a manual physical and digital reset:
What is the elevator showing (e.g., doors parked open, trapped between floors, vibrating)? Are you currently able to access the fault history log ? Drive errors usually point to the regenerative drive
The car has traveled past the terminal landings (top or bottom floor) and tripped the mechanical final limit switch.
The Schindler 5500 is a gearless traction elevator equipped with the Miconic MX microprocessor controller. Error codes are displayed on the or via the SML (Schindler Mobile Link) diagnostic tool. Codes are grouped by subsystem: drive, door, communication, safety chain, and position reference.
The on the main board.
Causes: Misaligned landing door interlocks, a defective light curtain (photoeye), or worn-out gate switch contacts.
For persistent or complex faults, a systematic approach is necessary. The following guides address common, difficult-to-diagnose scenarios confirmed through service records.
