Lift Door Drive Controller Elevator Door Machine Inverter YS-K01Elevator Parts

1. General Information

• Manufacturer: Likely Yaskawa, Hyundai, or a specialized elevator component supplier (exact brand may vary).

• Model: YS-K01

• Type: Elevator Door Motor Drive / Inverter

• Primary Use: Controls the speed, torque, and positioning of elevator door motors (AC or DC brushless types).

2. Key Features & Functions

Primary Functions:

✔ Variable Speed Control – Adjusts door opening/closing speed for smooth operation.
✔ Torque Management – Prevents excessive force (safety compliance for door obstruction detection).
✔ Positioning Accuracy – Ensures doors align correctly with floor levels.
✔ Communication Interface – Connects with the elevator main controller (via relay signals or serial communication).
✔ Safety Features – Includes overcurrent, overload, and fault protection.

Technical Specifications (Estimated):

• Input Voltage: AC 200-240V (1-phase or 3-phase, depending on model)

• Output Power: Matched to door motor requirements (typically 0.2kW to 0.75kW).

• Control Method: Sensorless vector control or V/F (Voltage/Frequency) mode.

• Protection Ratings: IP20 (standard enclosure for indoor use).

• Compatibility: Works with brushless (BLDC) or induction motors used in elevator doors.

3. Common Applications

• Used in passenger & freight elevators for automatic door control.

• Compatible with:

  • Sliding doors (center-opening, single-speed, or telescopic types).

  • Hospital elevators (where gentle door operation is critical).

  • Older elevator modernization (replacing outdated door drives).

4. Troubleshooting & Common Issues

Symptoms of a Faulty YS-K01 Inverter:

⚠ Doors not opening/closing (motor not responding).
⚠ Jerky or uneven door movement.
⚠ Error codes/flashing LEDs (indicates drive faults).
⚠ Overheating or sudden shutdowns.

Diagnostic Steps:

1. Check power supply (voltage stability).

2. Inspect motor connections (phases, encoder if present).

3. Monitor error codes (refer to the inverter’s manual).

4. Test with a replacement unit (if available).

5. Replacement & Sourcing Options

Where to Buy?

• Elevator parts suppliers (e.g., ELEVATORPARTS.COM, Direct Elevator Parts).

• Industrial automation dealers (if compatible with Yaskawa/Hyundai drives).

• Online marketplaces (eBay, Alibaba – verify authenticity).

Installation Notes:

• Must be installed by certified elevator technicians (safety-critical component).

• Parameter tuning required (door speed, torque limits, etc.).
