Danfoss VLT Lift Drive Fact sheet

VLT® Lift Drive

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

Designed specically 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.

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 lter 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.
