Frequently Asked Questions
What is the difference between closed-loop and open-loop control in the 11LIFT inverter?
The 11LIFT series supports both modes: Closed-loop uses encoder feedback (PG card) for precise speed and position control—ideal for high-rise passenger elevators requiring smooth stops. Open-loop operates without encoders, suitable for simpler cargo lifts or cost-sensitive installations. The removable PG cards allow easy switching between modes.
Does the 11LIFT-22KW inverter support PMSM gearless motors?
Yes, the 11LIFT-22KW is specifically optimized for Permanent Magnet Synchronous Motor (PMSM) gearless applications. It includes an anti-rollback function that prevents the cabin from sliding backward when stopped, a critical safety feature for gearless elevator systems. The 0 Hz 200% torque output ensures reliable holding torque at standstill for 22KW motor loads.
What UPS operation modes are available for power failure scenarios?
The 11LIFT-22KW features multiple UPS operation modes to handle power interruptions: ARD (Automatic Rescue Device) mode for emergency evacuation to the nearest floor, continuous operation mode with external battery backup, and safe shutdown sequencing. The dual CPU architecture ensures control redundancy during power transitions, maintaining safety even during outages.
What brake unit capacity is built into the 11LIFT-22KW?
The 11LIFT-22KW includes a built-in brake unit (standard for 0.4–37 kW models) for dynamic braking and controlled deceleration. The integrated brake chopper handles regenerative energy during descent, protecting the drive and ensuring smooth braking performance for mid-rise passenger and commercial cargo elevators.
