WEG’s ADL500 inverter series for elevators
These cutting-edge drives are designed to redefine elevator technology
Over the last decade, transportation modes like trains, cars and aircraft have witnessed unprecedented technological evolution, encompassing safety, comfort and efficiency. Elevators have followed suit. This is where WEG’s ADL500 inverter series comes in.
The ADL500 series, certified to European standards EN81-20 and EN81-50, boasts pioneering features, including Safe Torque Off SIL3, Safe Brake Test (SBT), and the Safe Brake Control (SBC – SIL3) with EBC500 accessory, which allow to control and monitor motor brakes status and avoid any unintentional movement. This integrated and innovative approach to safety has allowed WEG to introduce a revolutionary new concept called “Zero contactors”.
In terms of comfort, ADL500 offers the new enhanced Elevator Position Control (EPC) algorithm ensuring optimal comfort into the cabin, direct approach, and precise floor levelling even in the most demanding environments.

What’s more, the new series offers energy-saving solutions like an Active Front End Power Supply unit for small elevators and a parameter to inform user about system regeneration capabilities. Other features include the stand-by function, where the power part of the drive is shut off to eliminate the energy consumption during the idle state, and energy peak shaving where external supercapacitors pack can be recharged during the braking energy regeneration.
WEG’s ADL500 series also facilitates seamless operator communication with the inverter. The dedicated WEG Liftouch free application for Android, IOS, and Windows platforms allows operations like the start-up, monitoring, tuning, alarm check and the communication with the inverter is possible both via Wi-Fi connection, if the operator is located on site, or via WEG Drives RMS (Remote Management System) portal wherever he is located. A full set of log-in profiles can limit the level of operation to each operator based on his skills.
