Reliable icon

Built to be reliable

Danfoss are known for their reliability and because of this they test all the drives they build like no one else. Every single unit is factory tested for up to 45 minutes at full load before it is despatched so you can be confident that your system will simply keep on running with the minimum amount of service when others have reached the end of the line.

Flexible icon

Flexible drive for new projects and retrofits

Designed for all motors and grid voltages, the Danfoss VLT Lift Drive is suitable for both traction and hydraulic elevators in open or closed loop systems. Fitting all common feedback systems, these VLT drives are quick to commission with just 10 parameters communicated with elevator terminology.

Repairs icon

Operation with any typical motor type

Using the Static Automatic Motor Adaption function for asynchronous and PM motors, you can commission quickly and easily without removing the ropes from the traction sheaves. With many other drives this is not the case and can lead to the time consuming process of having to remove the ropes.

Commission icon

Easy to commission

With dedicated software it’s easy to handle the drive’s setup and service. You can access the software at any time through the keypad which has a clear graphical display. The read-outs are simple, clear and include the scope function that presents analogue and digital data. Parameterisation is tailored to lifts, using language familiar to people in the elevation industry.

Easily upgrade obsolete lift drives with the LD 302

VLT Lift Drive Repair

The LD-302 has been designed to be an easy replacement for many older, obsolete lift drives. Additional features, compact design and easy commissioning make it ideal for replacing a wide range of obsolete drives from manufacturers like Yaskawa, Omron and Magnetek.

  • Patented Safe Stop technology for higher reliability and space saving
  • Choose from IP20, 21, 55 and 66 protection rating for flexible installation options
  • Dedicated lift functionality reduces total system costs and noise from the lift shaft
  • Integrated RFI filter and DC coils provides lower installation costs, reduces space requirements and complies easily with EMC and harmonics standards

How to find your VLT Lift Drive part number

The part number for your VLT LD 302 inverter drive can be located on a label stuck to the top of the drive. This is the number we will need if you need us to supply a replacement drive, or the number you should use to search for prices online.
