Danfoss VLT Lift Drive Fact sheet

VLT® Lift Drive

Developed specifically for lifts to provide reliable and excellent ride comfort. Operates without motor contactors and can be commissioned in less than 10 minutes.

2.1 million

Load cycles

Is the minimum life time of the VLT® Lift Drive at 16 KHz frequency and 45 °C

ambient temperature.

Designed specifically for lifts

The VLT® Lift Drive’s compact, rugged design is optimized for easy installation. Built in features ensure a long life of reliable operation, a smooth ride, and low total costs.

Easy commissioning with customized software

Setup and service is easily handled using the drive’s dedicated software, which can be accessed at your convenience via the graphical display, VLT® Control Panel LCP 102. Read-outs are simple and clear, including the scope function that presents analog and digital data.

With parameterization tailored specifically for lifts all settings use “elevator language”. This means that specialists are not required, as owners can set up and service their lift themselves in the shortest possible time.

Feature

Patented Safe Stop technology

IP 20, 21, 55, 66 protection rating

Dedicated lift functionality

Integrated RFI filter and DC coils

Operates without motor contactors

The patented Safe Stop function eliminates the need for motor contactors, increasing the reliability of the elevator installation, which is at least as safe as a solution with motor contactors.

An integrated RFI filter and DC coils eliminate the costly installation of external components. This reduces space requirements and eliminates a complex EMC-compliant wiring.

Reliable in all environments

The Lift Drive can be installed in challenging ambient conditions outside the control of the variety of available housing and protection classes. For example, a unique feature of the Lift Drive means that when the temperature rises, the drive maintains the output current so that only the switching frequency is derated.
