Fuji Electric FRN0019LM2A-4E FRENIC-Lift Inverter (7.5 kW, 18.5 A, 400V)
The Fuji FRN0019LM2A-4E is a 7.5 kW (18.5A) high-precision elevator drive. Designed for geared and gearless motors, it features SIL3-rated STO safety, 200% overload capacity, and supports UPS/battery rescue operations for maximum reliability.
- Universal Motor Compatibility: Capable of driving both standard induction motors (geared) and high-efficiency permanent magnet synchronous motors (gearless/MRL).
- Advanced Functional Safety: Equipped with Safe Torque Off (STO) compliant with SIL3/PLe standards, eliminating the need for some external safety contactors.
- High Overload Performance: Provides 200% of rated current for 3 seconds, ensuring powerful torque during the lift’s critical start-up phase.
- Emergency Rescue Support: Dedicated modes for power failures, allowing the lift to run on 24V DC auxiliary power and external UPS or batteries (>48V DC) to evacuate passengers safely.
- Quiet and Smooth: High carrier frequency control reduces motor noise and vibration, providing a premium “silent” travel experience.
- European Market Standard: The “E” suffix indicates the unit is optimized for European standards and regulations.

Product Description
Where is it used in an elevator? Think of the Fuji FRN0019LM2A-4E as the “gas pedal” and the “smooth brakes” of your elevator. While the motor does the heavy lifting, the inverter sits inside the metal control cabinet (usually in the machine room or at the top of the shaft) and tells the motor exactly how fast to turn.
Without this device, an elevator would start and stop instantly like a light switch, which would be very uncomfortable and dangerous for passengers. The FRN0019LM2A-4E takes the raw electricity from the building and transforms it into a smooth “curve.” This means the lift starts slowly, speeds up gently, and slows down so perfectly that you barely feel it stop level with the floor.
Safety and Reliability: In the B2B engineering world, reliability is key. This Fuji drive includes Safe Torque Off (STO), a digital safety “kill switch” that can stop the motor immediately if a problem is detected, meeting the strictest European safety laws (EN 81-20). Furthermore, if the building loses power, this inverter knows how to talk to a battery system to move the lift to the nearest floor so nobody gets stuck inside.
Frequently Asked Questions (FAQs)
Q1: Can I use this inverter for both old geared motors and new gearless systems?
Yes. The FRN0019LM2A-4E is universal. It can be configured for older induction motors (asynchronous) and modern permanent magnet motors (synchronous), making it perfect for both new buildings and modernization projects.
Q2: What happens if the electricity goes out while people are in the lift?
The inverter has a built-in Rescue Operation mode. It can be powered by a standard 220V UPS or a 48V DC battery pack to move the elevator slowly to a floor level and open the doors.
Q3: Is the setup difficult for technicians?
Fuji Electric provides a dedicated Auto-Tuning feature. This allows the inverter to “learn” the motor’s electrical characteristics automatically, which reduces setup time and prevents manual programming errors.
Q4: Do I need a special keypad to program it?
While the unit can operate via terminal commands, an optional Multi-function Keypad (TP-A1-LM2) is highly recommended for B2B applications. It allows for easy parameter adjustments, copying settings between units, and detailed fault monitoring.
