Main features & Overview


In the last decade the elevators have been under a tremendous evolution from the technology standpoint like never before. Safety, comfort travel, efficiency, reliability, remote access combined with the use of smartphones and tablets are the major changes that we daily experience versus the old generation systems.

Gefran has developed the new ADL500 inverter series specific for elevators EN81-20 / EN81-50 certified.

The series is composed of three lines ADL550, ADL530 and ADL510 designed to answer the requirements of high rise, medium rise and low rise buildings, without to forget the big market of the modernization.

ADL510: designed to be simple and easy to install in case of asynchronous motors typical of low-rise buildings or modernization both in open and close loop.

ADL530: designed to control both geared and gearless motors integrated On-board Universal encoder interface (EnDat, SinCos, BiSS and Digital Incremental) and integrated CAN port for communication by CANopen 301 and CANopen Lift 417 are ready to use.

ADL550: specific for installations requiring high levels of performance with advanced safety features, such as Safe Torque Off SIL3 (Phase contactor-less), Safe Brake Test (SBT) to check the motor brakes effectiveness, and the Electronic Brake Control (EBC) SIL3* that replaces the electro-mechanical brakes contactors by internal electronics (Brake contactor-less).



  • Functions to void roll-back and suppress vibrations upon start-up.
  • “Direct Landing” positioning at the floor.


  • Safe Torque Off (STO-SIL3): Can use drive with no output contactors.
  • Electronic Brake Control (EBC500-SIL3)*: External device to replace electromechanical brake control relays 
  • Safe Brake Test (SBT): specific function to check the motor brakes effectiveness


  • Universal multi-encoder card integrated (ADL530 and 550)
  • Integrated module for emergency DC battery power supply
