IDEEI Z3300 (open-loop, 2.2-37kW, 220-240V / 380-480V branches) and D3300 (closed-loop, 2.2-45kW at 380-440V) elevator inverters on one selection page, with encoder-free SVC or FVC feedback control, RS485 and elevator I/O.
Choose between two dedicated elevator drive configurations: Z3300 for encoder-free open-loop control of suitable asynchronous motors, or D3300 for closed-loop vector control with a compatible encoder and separately selected PG card. Z3300 covers 2.2–7.5kW at 220–240V and 3.7–37kW at 380–480V; D3300 covers 2.2–45kW at three-phase 380–440V. The series headline combines both ranges; voltage and power availability differ by model.
The Z3300 is the open-loop branch: encoder-free vector control for cargo and passenger elevator projects, in a 220–240V branch (2.2–7.5kW) and a 380–480V branch (3.7–37kW). The D3300 is the closed-loop branch, with the model-by-model currents in the table — for example the D3300-2.2KW-4 at 6.5A input / 5.1A output and the D3300-11KW-4 at 29.0A / 27.0A. Choose open-loop where sensorless control fits the application, and closed-loop where the project specification calls for closed-loop control; do not order from the 2.2–45kW headline range alone.
For the modernization decision in full, see our Elevator Drive Modernization: 7 Signs Your Lift VFD Is Due for an Upgrade — it lists seven signs that a lift VFD is due for an upgrade.
Z3300 provides sensorless control without encoder feedback. D3300 supports SVC and feedback vector control (FVC), with asynchronous motor and PMSM support subject to the correct encoder configuration.
Preset speeds and acceleration/deceleration curves support elevator motion profiles. D3300 adds multi-segment S-curves and startup pre-torque compensation for ride comfort.
Brake, contactor, overspeed, speed-deviation and motor protection functions support system integration.
RS485 and scalable I/O functions support control-panel and modernization projects where listed.
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.

Open-loop vs closed-loop: the Z3300 estimates motor operation without encoder feedback and suits standard elevator duties; the D3300 uses encoder feedback (FVC) for 200% startup torque at 0Hz, PMSM support and speed stability of ±0.05%.
Closed-loop models do not include a PG card free of charge; the PG card is priced separately.
| PG Card | Price (USD) |
|---|---|
| 1387 Encoder Feedback | $17 |
| 1313 Absolute Encoder (Heidenhain ECN413) | $39 |
| ABZ Encoder | $19 |
| MCTC-PG-E (SIN/COS, for synchronous motors) | $19 |
| MCTC-PG-F1 (Absolute Encoder) | $39 |
Select the PG card by encoder model, signal interface, supply voltage and drive hardware revision. Power rating alone does not establish compatibility; confirm the exact card before ordering.

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.
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.
Z3300 is the encoder-free open-loop choice for suitable asynchronous motors. D3300 supports asynchronous motors and PMSM; closed-loop operation requires a compatible encoder and PG card. Send the motor nameplate and encoder details for selection.
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.
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.
No. Rated motor current, elevator load, speed, duty cycle, braking energy, motor type, encoder, cable length and ambient conditions all affect final selection.
Send the motor nameplate, elevator type, load, speed, travel height, floor count, encoder, brake arrangement, control-panel information, quantity and destination.
Send the required electrical and application data, quantity and destination. Our team will confirm the suitable model, options and quotation scope.
