FST‑100 Compact Housing Door Drive VFD: Compact Door Motor Controller for Elevator Retrofit & Automatic Door Replacement (200W–750W)

FST‑100 Compact Housing Door Drive VFD — Drop‑in Replacement Door Motor Controller for Elevator Modernization & Retrofit Projects (200W‑750W)

The compact‑cased AnyHz FST‑100 retains the full feature set of the standard FST‑100 series but adopts a slim redesigned housing to fit cramped control cabinets. This drop‑in door controller is purpose-built to replace legacy door operators including Monarch NICE-D-A-SOP2 and STEP SM-01-DP.

Combining integrated door logic and motor drive hardware, it removes the need for an external PLC and cuts wiring workload significantly. It supports both AC asynchronous motors and permanent magnet synchronous motors (PMSM), with one-click door width learning, real-time obstacle detection and power-off anti-pinch safety functions. It is the ideal retrofit solution for elevator renovation, narrow cabinet upgrade and replacement of existing automatic door units. It delivers smooth, quiet and reliable door motion without heavy rework on original wiring.

• Slim Compact Housing: Optimized for narrow elevator control cabinets, perfect for retrofit & modernization projects with limited installation space
• Drop-in Replacement Compatibility: Direct substitute for mainstream elevator door drives; minimal modification to existing wiring harness
• Dual Motor Support: Drives both AC induction and PM synchronous motors without complicated parameter reset
• Intelligent One-Click Learning: Auto door width calibration cuts site commissioning time by up to 80%
• Advanced Safety Protection: Obstacle detection, power-off anti-pinch and real-time torque monitoring to meet EN81‑20 safety standards
• Easy Commissioning: Auto-tuning and automatic motion curve generation reduce on-site debugging labor
• Full Electrical Protection: Over/under voltage, overcurrent, short circuit, and phase loss protection to safeguard door systems

One-click door width self-learning enables the unit to automatically measure full door travel range. No manual parameter entry required. Simply activate learning mode and the VFD generates optimized S-curve motion profiles matching your door’s mechanical characteristics.

• Automatic detection of full open/close limit positions
• Self-calibration for door mass and friction variation
• Optimized curve output to lower mechanical impact and wear

The compact FST‑100 provides two flexible control strategies. Speed control suits simple on/off trigger applications, while distance control delivers precise positioning for advanced retrofit requirements. Distance mode unlocks partial opening, nudging and accurate floor leveling features for elevator upgrades.

• Speed mode: 0–99Hz frequency regulation for basic door operation
• Distance mode: High-precision position control with encoder feedback
• Smooth mode switching via parameter setting or serial communication

Built-in torque monitoring and speed feedback analysis identify obstructions in real time. If the detected resistance exceeds predefined safety thresholds, the door reverses direction or stops instantly to protect passengers and mechanical components. The power-off anti-pinch function maintains safety protection even when main power fails during renovation scenarios.

• Multi-level adjustable torque sensitivity
• Instant reverse on obstacle detection (<100ms response time)
• Optional battery backup module for power-fail safety protection

For elevator retrofit jobs, gate knife distance learning precisely calibrates the engagement point between car door and landing door. This achieves synchronized door movement and eliminates the mechanical jolt commonly seen in outdated door drive systems, improving passenger comfort after elevator modernization.

• Automatic gate knife position recognition
• Synchronized car & landing door operation
• Reduced mechanical noise and component wear

FST‑100 Compact automatically identifies door system inertia by measuring operating kinetic energy, friction and self-closing force. It dynamically adjusts output torque across the full door travel stroke, compensating for temperature drift, mechanical aging and varying door weight after long-term operation.

• Real-time friction and inertia calculation
• Automatic torque compensation
• Stable performance throughout the whole service cycle

Control via digital I/O terminals or RS‑485 Modbus RTU serial communication. It can connect to existing elevator main controllers, building automation systems or standalone push buttons during retrofit. The flexible interface accepts open collector and push-pull encoder signals for both AC and PM motors.

• 8 programmable digital inputs
• 3 relay outputs for working status indication
• RS‑485 port for remote monitoring and parameter adjustment

Compact FST‑100 is engineered for elevator renovation projects. It acts as a direct replacement for old door operators. Gate knife distance learning ensures smooth synchronization between car door and landing door, and obstacle detection complies with EN81‑20 safety requirements.

Yes, FST‑100 Compact is designed as a drop-in replacement for Monarch NICE-D-A-SOP2, STEP SM-01-DP and other mainstream elevator door drives. It shares compatible I/O interfaces and offers more convenient learning functions. We supply wiring conversion guides to simplify retrofit installation. Dual AC & PM motor support brings greater flexibility than many competing door operators.

Speed control mode uses frequency commands (0-99Hz) to regulate door speed; it works well for simple retrofit door applications. Distance control mode relies on encoder feedback for precise position control, enabling advanced features including partial opening, exact floor leveling and nudging. Distance mode is recommended for most elevator upgrade jobs, while speed mode fits simple gate retrofits. Users can switch modes by modifying parameters.

Not mandatory. FST‑100 Compact can run open-loop magnetic flux vector control without an encoder for basic retrofit door applications. If you need distance control and high-precision positioning, an ABZ incremental encoder is required. Both open collector and push-pull encoder types are supported. Encoders are strongly recommended for elevator door retrofits, while simple gate upgrades can work encoderless.

Trigger learning mode via physical button or communication command. FST‑100 Compact will drive the door through full open/close cycles automatically, measuring travel range, friction and inertia. It then generates optimized S-curve motion profiles. The whole process takes only 2–3 minutes and removes tedious manual parameter setup, saving plenty of on-site retrofit time.

FST‑100 Compact integrates EN81‑20 compliant safety features such as obstacle detection, power-off anti-pinch and torque monitoring. The drive carries CE certification. For full elevator system certification, make sure your whole installation complies with local safety codes for control architecture and safety circuits. We provide technical documentation to support certification work.

Yes, FST‑100 Compact supports high-duty cycle operation with 150% overload capacity and robust thermal design. For heavy-duty renovation scenarios such as subway platform doors with more than 1,000 cycles per day, FST‑100‑0R4S2 or FST‑100‑0R7S2 with forced air cooling is recommended. Built-in protection mechanisms ensure stable 24/7 operation after retrofit.
