~ New cutting edge drives are designed to redefine elevator technology ~
In a new development in elevator technology, motor and drive supplier WEG has introduced the ADL500 inverter series. 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 and WEG, driven by a commitment to innovation, robust R&D and collaborative partnerships with leading universities, has now released the ADL500 series.
The ADL500 series, certified to European standards EN81-20 and EN81-50, seamlessly combines the success of its predecessor, the ADL300, with innovative concepts that shape the future of elevator technology. This new offering boasts a host of pioneering features, including Safe Torque Off SIL3, Safe Brake Test (SBT), and the Safe Brake Control (SBC – SIL3) with EBC500 accessory, which allow operators to check motor break status and avoid any unintentional movement.
WEG has also introduced its pioneering Zero Contactors concept. Contactors are switches commonly used in inverters to switch between circuits, and this new technology removes the need for them, with its Enhanced Elevator Position Control (EPC). The EPC algorithms ensure optimal comfort, direct approach, and precise floor levelling even in the most demanding environments. What’s more, the series offers an array of energy-saving solutions, aligning with the global shift towards sustainable practices.
WEG has introduced green technologies with this latest offering, such as regeneration through the new AFE200 size for smaller elevators, a standby function for eliminating idle-state energy consumption, and energy peak shaving through rechargeable external supercapacitors to avoid spikes in consumption.
Recognising the prevalence of smart devices and IoT technology, WEG’s ADL500 series facilitates seamless operator communication with the inverter. The dedicated WEG_Liftouch application for Android, IOS, and Windows platforms enables remote startup, monitoring, tuning, and alarm checks. Whether onsite with a Wi-Fi connection or through the WEG Drives RMS (Remote Management System) portal, operators can remotely manage operations with ease and precision.
Comprising three distinct models — the ADL550, ADL530, and ADL510 — each tailored to suit high-rise, medium-rise, low-rise, or modernisation projects.
“The ADL550 is equipped with a comprehensive safety package and enhanced EPC,” explained Karim Boudaoud, product manager at WEG Automation Europe. “This model is ideal for high-rise buildings, while the ADL530 accommodates both asynchronous and synchronous motors, featuring an integrated universal multi-encoder interface, with a range of encoders (EnDat, SinCos, BiSS and Digital Incremental) already integrated into the inverter. This innovative design eliminates the need for additional cards, streamlining stock management and setup.”
The ADL510 is designed for asynchronous motors typical of low-rise buildings or modernisation projects and offers a straightforward installation process. With a power range of between 4 and 22 kW, it caters to a wide range of applications.
The ADL500 inverter family embraces a smart approach and sustainable practice to offer innovative new solutions in elevator technology. With pioneering new concepts putting safety, comfort and efficiency at the forefront, this new offering is an exciting new development in the elevator market.
