IDEEI D3300-P closed-loop elevator inverter covers 3.7-37kW with encoder feedback, dual-CPU control, 200% zero-speed torque and UPS rescue functions.
D3300-P is a closed-loop elevator-dedicated drive for applications requiring encoder feedback, strong zero-speed torque, anti-rollback behavior and elevator trip diagnostics. Catalog voltage branches define the publishable range; exact current and order code require selection confirmation.
Encoder feedback supports high low-speed precision and controlled torque for elevator motion.
S-curve, pre-torque and direct-travel functions support smooth starting, travel and landing when correctly commissioned.
Elevator-specific outputs and protections coordinate the drive with the wider control and safety system.
PMSM and asynchronous motor projects require the matching motor parameters, encoder and PG interface.
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.

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.
Motor support depends on the selected D3300-P control mode and hardware. Send the motor nameplate and encoder details so the correct model, PG card and tuning procedure can be confirmed.
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.
