Technical Specifications

Dedicated Elevator Inverter for Lift Applications

The Fuji FRENIC-Lift FRN11LM1S-4EA is not a general-purpose inverter; it is designed specifically for elevator operation. Elevator drives require accurate motor control, strong overload performance, smooth acceleration and deceleration, and reliable braking behavior. The FRENIC-Lift platform is developed to meet these requirements in professional lift systems.

With its 11 kW / 15 HP capacity and 24.5 A rated output current, this model is suitable for medium-capacity elevator applications using 400V three-phase power.

Compatible with Geared and Gearless Elevator Motors

The FRN11LM1S-4EA can be used with both induction motors commonly found in geared elevator systems and PM synchronous motors used in modern gearless elevator machines.

This flexibility makes the inverter suitable for:

• Elevator modernization projects
• Geared traction elevator systems
• Gearless PM motor elevator systems
• Machine room elevator applications
• Professional lift control panel installations

High Overload Capacity for Elevator Duty

Elevators require strong short-term torque during starting, acceleration, and load changes. The Fuji FRENIC-Lift FRN11LM1S-4EA provides 200% overload capability for 10 seconds, helping the drive handle demanding elevator operating conditions.

This high overload performance supports smooth starts, stable acceleration, and reliable operation under passenger load variation.

Communication and Elevator Control Integration

The inverter supports Modbus RTU over RS-485 and DCP03 communication, allowing integration with compatible elevator controllers and control panels.

These communication features help simplify system integration, parameter monitoring, and elevator drive control in professional installations.

Built-in Braking Transistor

The FRN11LM1S-4EA includes a built-in braking transistor. For braking energy dissipation, an external brake resistor can be connected to the P(+) and DB terminals.

In elevator systems, braking energy must be managed correctly to help prevent DC bus overvoltage and support stable drive operation during deceleration and downward travel.

Keypad Sold Separately

Please note: The TP-G1-ELS multifunction keypad is not included with this inverter. The keypad is available as a separate product and can be ordered here:

Fuji Electric TP-G1-ELS Multifunction Keypad

The TP-G1-ELS keypad provides a multifunction LCD interface and is designed for parameter setting, monitoring, and easier operation of Fuji FRENIC-Lift inverters.

Installation Notes

Installation and commissioning should be performed by qualified elevator technicians or electrical professionals familiar with Fuji FRENIC-Lift inverters, elevator control panels, motor parameters, encoder interfaces, braking resistor selection, and applicable safety standards.

• Confirm motor type before commissioning: induction or PM synchronous
• Check encoder voltage and signal compatibility
• Use suitable braking resistor according to system requirements
• Apply external EMC filtering where required by the installation standard
• Ensure proper panel ventilation for forced air cooling
• Follow Fuji Electric installation and parameter setting instructions
