Lift drive inverter ranges from Gefran

26 April 2010

The ADL and AVRy lift drive inverters from Gefran cover entry level to advanced performance for power ranges up to 90kW, with a strong emphasis on energy efficiency and application versatility.

The ADL100 series offers sensorless vector control of geared lift applications at speeds of up to 1.2m/s. The modular design includes a simplified I/O configuration but a fully featured lift control capability is provided, with integrated braking control and wireless remote interfacing for Bluetoothdevices. An integrated RS232 serial communications port is also included with Modbus RTU protocol and set-up/diagnostics made easy with a PC programming wizard or an optional multilingual keypad.

The ADL 200 series builds on these features with advanced characteristics for geared or gearless lift systems in standard or machine room-less installations driven by asynchronous induction motors or synchronous brushless motors. The versatile ADL200 series is based on an advanced 32-bit hardware platform with a wide range of pre-defined drive configurations plus interfaces for multilevel I/O control and encoder options which include incremental, sinusoidal and EnDat absolute. In addition a wide choice of communications fieldbus options ensure maximum interfacing capability.

The AVRy series inverters feature built-in ‘clean energy’ power recovery technology for reduced operating system costs and energy savings for geared and gearless lift systems with synchronous or asynchronous motor ratings to 15kW and speeds to 5m/s.

Motor control includes space vector modulation for whisper quite operation and dedicated elevator features are also offered, including smooth start, multi-speed, braking, output contactor and door control functions. Gefran lift drives feature controls for independent management of short floors and position controls for storing floor distances.
