Applicable Systems
Kone Elevator
Symptoms
Position fault. The car position data is invalid or inconsistent. The controller cannot determine theelevator position.
Possible Causes
- Position reference lost after encoder reset
- Position sensor signal invalid
- Position calculation overflow or underflow
- Position data corrupted in memory
- Re-leveling or re-learning required
Troubleshooting Steps
- Step 1: Check the equipment status and fault indicators to confirm the active fault code
Fault indicator or HMI displays code 0101 as active - Step 2: Verify all electrical connections, wiring harnesses, and connector seating
All connections secure, no corrosion, loose pins, or damaged wires - Step 3: Check encoder cable and connector at both motor and drive/controller ends
Cable intact, connector fully seated, no bent or corroded pins - Step 4: Verify encoder signal integrity with an oscilloscope if available
Signal waveform normal with clean edges, no dropouts or noise - Step 5: Check for mechanical interference, coupling slippage, or excessive load on the axis
No mechanical interference, coupling secure, load within rated capacity - Step 6: Verify the axis reference point and home position are valid
Axis has valid reference point, position data is consistent - Step 7: Replace encoder if signal is consistently absent or corrupted after cable checks
New encoder provides stable, clean signal
How to Reset
To reset: 1) Identify and fix the root cause described in the fault symptoms. 2) Press RESET on the HMI or controller, or power-cycle the equipment. 3) If the fault recurs, contact manufacturer service. Caution: Document the fault code and context before resetting.
Frequently Asked Questions
- Q: What does fault code 0101 mean on the Kone Kone Elevator?
Fault 0101 indicates a position or encoder-related fault. The control system has detected an issue with axis positioning, speed feedback, or encoder signal. Check the encoder cable and motor feedback system.
- Q: Can I continue operating the equipment with fault 0101 active?
No. The equipment has detected a fault condition and has taken protective action (typically stopping or derating). Continuing to operate without fixing the root cause may cause further damage. Always investigate and fix the fault before resuming operation.
