11LIFT Closed-Loop Elevator Inverter

The IDEEI closed-loop elevator inverter uses feedback vector control (FVC) and encoder feedback to manage elevator motion from zero speed. Covering 2.2kW to 15kW at three-phase 380-440V, it is designed for applications that require strong starting torque, accurate speed regulation, smooth S-curve travel and dependable brake coordination.

Closed-Loop Control Features

🎯 Encoder Feedback Precision

FVC reads motor speed and position feedback through a matching PG card, supporting a 1:1000 speed range and ±0.05% speed stability.

⚡ Zero-Speed Starting Torque

Up to 200% startup torque at 0Hz supports controlled holding and confident starts before the elevator begins to move.

🛡️ Elevator Safety Logic

Brake and contactor control, overspeed protection, speed-deviation detection, slow-down judgment and motor-temperature monitoring are integrated.

🏢 Smooth Ride Functions

Flexible startup curves, multi-segment S-curves, direct travel ride and three startup pre-torque compensation modes help improve ride comfort.

Standard within this listed range: the manual states that 15kW and below models include a built-in braking unit; connect the correctly selected external braking resistor. The product introduction also specifies a built-in DC reactor.

Encoder configuration: the encoder type, voltage, signal format, PPR and matching PG card must be confirmed for the selected motor. Encoder cards and emergency power arrangements are configuration-dependent.

Applications and Selection Information

Suitable for passenger elevators, freight elevators, villa elevators and modernization projects that require encoder-feedback control. For selection, provide the motor nameplate, asynchronous/PMSM type, encoder details, rated speed, traction ratio, car load, travel speed, braking resistor requirement, power supply and quantity.

Installation conditions: rated operation is below 1,000m altitude and from -10°C to 40°C. Derate 1% for every additional 100m above 1,000m and derate above 40°C; the stated maximum ambient temperature is 50°C.

Frequently Asked Questions

Does closed-loop control require an encoder?

Yes. FVC depends on motor feedback through a compatible encoder and PG card. Confirm the feedback hardware before ordering.

Can it control a PMSM elevator motor?

Yes. The manual supports PMSM and asynchronous motors. PMSM control requires the correct encoder setup and motor auto-tuning.

Is a braking resistor still required?

The listed models include a braking unit, but the appropriate external braking resistor must still be selected and connected.

Does it support emergency evacuation?

The manual provides an emergency evacuation solution using a 48V battery supply. Confirm the complete rescue-power configuration for the project.
