IDEEI 11LIFT closed loop elevator inverter, 4kW-30kW, 3-phase 380-440V. FVC vector control with 200% starting torque at 0Hz and ±0.05% speed accuracy. Note: closed-loop operation requires a PG card plus motor encoder (322-ABPG or 322-SCPG, ordered separately). Built-in DC reactor, braking unit and 48V emergency rescue. CE certified, 24-month warranty.
The IDEEI 11LIFT series is a dedicated closed loop elevator inverter for passenger lifts, freight elevators and modernization projects. With FVC closed-loop vector control (PG card + encoder feedback), it delivers 200% starting torque at 0 Hz and ±0.05% speed accuracy for smooth, direct-landing ride comfort. A built-in DC reactor and braking unit reduce peripheral costs, and the 48V battery emergency rescue function keeps passengers safe during power failures.
FVC closed-loop vector control with PG card and encoder feedback provides 200% starting torque at 0 Hz, a 1:1000 speed range and ±0.05% speed accuracy. Four groups of S-curve acceleration/deceleration ensure jerk-free, comfortable rides and precise direct landing.
Overspeed protection, speed deviation detection, brake contactor control, output contactor control and starting pre-torque compensation are built in. During a power failure, the 48V battery-powered emergency rescue function moves the car safely to the nearest floor.
Drives both asynchronous (induction) motors and permanent magnet synchronous motors (PMSM). Motor auto-tuning works with or without load, and multiple encoder interfaces are supported (SIN/COS, UVW, ABZ incremental) via the matching PG card.
The integrated DC reactor improves power factor and the built-in braking unit handles regenerative energy, cutting the cost and cabinet space of external peripherals. Independent air duct and conformal coating ensure reliability in machine-room environments.
This is a closed-loop elevator inverter: FVC closed-loop vector control must run with a PG card and a motor encoder for speed/position feedback. The PG card is an optional accessory and is not included with the inverter. Please order it together with the inverter, or contact us to confirm the correct card for your encoder.

Yes. FVC closed-loop operation must have a PG card plus a motor encoder for feedback; the card is an optional accessory ordered separately. Choose 322-ABPG (15V) for open-collector/push-pull incremental encoders, or 322-SCPG (5V) for SIN/COS encoders — or send us your encoder type and we will confirm the correct card.
Choose closed-loop (this page) when your elevator motor has an encoder and you need 200% starting torque at 0 Hz, ±0.05% speed accuracy and the highest ride comfort — typical for passenger elevators. Open-loop SVC suits simpler, encoder-less applications; see our open-loop elevator inverter variant page for that option.
It supports both asynchronous (induction) motors and permanent magnet synchronous motors (PMSM). Motor auto-tuning runs with or without load, and multiple encoder interfaces are supported through the matching PG card (SIN/COS, UVW, ABZ incremental).
The inverter has a built-in emergency rescue function powered by a 48V battery. When mains power fails, the inverter switches to battery power and moves the car at low speed to the nearest landing so passengers can exit safely.
No. The 11LIFT series has a built-in DC reactor and a built-in braking unit, which improves power factor and reduces the cost and cabinet space of external peripherals. You only need to add an external braking resistor matched to your application.
