IDEEI 11LIFT Open-Loop & Closed-Loop Elevator Inverter 2.2-37kW

The 11LIFT platform covers both open-loop sensorless vector control (SVC) and closed-loop feedback vector control (FVC) in the same 2.2-37kW range, together with elevator-specific brake, contactor, protection and rescue functions. The open-loop version needs no encoder feedback and delivers 180% startup torque at 0.5Hz, a 1:100 speed adjustment range and ±0.5% speed stability; the closed-loop version adds encoder feedback for higher precision. Exact current rows are verified to 15kW at 380V; catalog branch ranges cover additional powers that require exact-order confirmation.

Key Features & Benefits

Closed-Loop Vector Control

Encoder feedback supports high low-speed precision and controlled torque for elevator motion.

Elevator Ride Functions

S-curve, pre-torque and direct-travel functions support smooth starting, travel and landing when correctly commissioned.

Brake & Contactor Logic

Elevator-specific outputs and protections coordinate the drive with the wider control and safety system.

Motor & Encoder Options

PMSM and asynchronous motor projects require the matching motor parameters, encoder and PG interface.

Open-Loop Sensorless Control

Sensorless vector control without encoder feedback for suitable asynchronous motors. It delivers 180% startup torque at 0.5Hz, a 1:100 speed adjustment range and ±0.5% speed stability, and needs no PG card.

Open-Loop and Closed-Loop Versions

This page covers both versions of the IDEEI 11LIFT elevator inverter – the open-loop version and the closed-loop version – in the same power range, 2.2-37kW. The closed-loop version offers higher control accuracy and smoother operation and must be used with a PG card (the PG card is priced separately).

Version	Control mode	PG card	Typical use
Open-Loop	Sensorless vector control without encoder feedback; 180% startup torque at 0.5Hz; 1:100 speed adjustment range; +/-0.5% speed stability accuracy	–	Passenger elevators, cargo elevators, villa elevators, hospital lifts, elevator modernization, control-panel and OEM projects
Closed-Loop	Feedback vector control with matching encoder and PG card; 200% startup torque at 0Hz; 1:1000 speed adjustment range; +/-0.05% speed stability accuracy	Required (priced separately)	Passenger elevators, cargo elevators, villa elevators, hospital lifts, elevator modernization, control-panel and OEM projects

Verified Model Selection

The table separates verified published data from project-dependent choices. Match the product by electrical ratings and application conditions; do not select from the headline power value alone.

Control-panel and OEM projects

Information Required for Selection

Traction or door motor nameplate: power, voltage, current, frequency and motor type
Encoder type, signal format, resolution and required PG card for closed-loop systems
Elevator type, rated speed, load, travel height, floor count and duty cycle
Brake coil, braking resistor, UPS rescue supply and safety-chain arrangement
Control interface, I/O count, communication protocol and panel compatibility
Site temperature, altitude, cable length, quantity and destination

A dependable quotation requires the complete operating profile, not only the nominal power. IDEEI reviews voltage, current, source or motor data, duty, environment, required options and destination together so the final configuration, accessories, protection devices and commercial scope can be stated clearly.

Engineering & Installation Notes

The inverter or integrated controller is one part of the elevator control and safety system. Door circuits, mechanical brake, safety chain, final limits, rescue power and inspection controls remain system-level responsibilities. Commission motor data and encoder interfaces only with the car secured and qualified personnel present. Verify braking energy, resistor duty, contactor sequence and local elevator code before passenger service.

Installation and commissioning must be completed by qualified electrical personnel. Isolate all energy sources before wiring, verify terminal functions against the current manual, provide protective devices and grounding, and apply the published derating guidance for altitude, temperature, enclosure and cable length. Product-page data supports preliminary selection and does not replace project engineering or local code compliance.

Frequently Asked Questions

Can this drive control both PMSM and asynchronous motors?

Motor support depends on the selected 11LIFT Closed-Loop control mode and hardware. Send the motor nameplate and encoder details so the correct model, PG card and tuning procedure can be confirmed.

What is the difference between open-loop and closed-loop control?

Open-loop vector control estimates motor operation without encoder feedback. Closed-loop vector control uses a compatible encoder and PG interface for higher low-speed and zero-speed performance.

Is UPS rescue operation included?

UPS or battery rescue functions are series- and project-dependent. The emergency power rating, wiring, travel logic, contactors and local safety requirements must be engineered as a complete system.

Can the inverter be selected only by motor kW?

No. Rated motor current, elevator load, speed, duty cycle, braking energy, motor type, encoder, cable length and ambient conditions all affect final selection.

What should be sent for a quotation?

Send the motor nameplate, elevator type, load, speed, travel height, floor count, encoder, brake arrangement, control-panel information, quantity and destination.
