Reliable operation and excellent ride comfort

The VLT® Lift Drive is designed to provide reliable operation and excellent ride comfort for a minimum of 2.1 million cycles when running at an ambient temperature of below 45°C. Ideal for new projects or for retrofits, it operates without motor contractors and can be quickly and easily commissioned in less than 10 minutes.

Designed for all motors, including asynchronous, induction, permanent magnet, copper rotor and direct online PM motors, the VLT Lift Drive is suitable for both traction and hydraulic lifts in open- or closed-loop systems.

The compact design and intelligent cooling concept means it easily fits even into small installation spaces. And a range of built-in features eliminates the need for extra components. Scalable RFI filters minimize electromagnetic interference, integrated DC chokes suppress harmonics while ensuring the drives meet relevant EMC standards, and step-up, step-down transformers are not required.

Supply voltages and power range

380-400 V…4-55 kW

Features and benefits

Travel comfort is enhanced thanks to a range of noise-reducing features
Energy savings can be achieved as cooling fans run only when absolutely necessary
The drive is quick and easy to commission as it fits all common feedback systems and there are just 10 parameters to set
The drive operates reliably in harsh conditions due to specially coated circuit boards – Components remain firmly in place in environments with high degrees of vibration thanks to the ‘ruggedized’ version

Features and benefits	– Assets are protected thanks to specially designed software that prevents, for example, water hammering – Energy efficiency is maximized as a result of the drives control algorithms and design which focus on reducing heat loss – High energy savings related to air conditioning are ensured due to the unique back-channel-cooling concept that transfers 90% of heat away from the room – Electromagnetic interference and harmonic distortion are reduced thanks to the built-in, scalable RFI filter and integrated DC link chokes – Perfect system integration and adaptation to the application are possible due to freely programmable warnings and alerts 3–8% energy savings are achieved as a result of Automatic Energy Optimization
Applications	Centrifugal pumps and blowers, positive displacement blowers.
