O produkcie
Safe and reliable operation
Variable Frequency Drive AT24 line LE is designed to control a synchronous and asynchronous, gear and gearless elevator winches. Triol AT24 VFD line LE is specially designed to ensure safe and reliable operation of elevator equipment and has advanced functionality for modern elevators. Programmable inputs and outputs allow configuring Triol AT24 VFD line LE to operate with any type of Variable Frequency Drive.
Unique algorithms
Triol AT24 VFD line LE is able to work with three types of encoders (incremental, absolute, sine/cosine) without the use of additional units. Unique Triol algorithms of sensor and sensorless vector control, algorithms of specialized lift functionality, slip compensation, anti-rollback algorithms are implemented in Triol AT24 VFD line LE.
Automatic measurements
Automatic measurement of motor parameters makes the setting process of Triol AT24 VFD line LE easy and precise. The function of measuring parameters without the need for motor rotation becomes indispensable when the elevator car is already mounted. Operation with UPS ensures a reliable power supply and elevator operation. Setting up and controlling Triol AT24 VFD line LE is easy due to the use of: Wi-Fi adapter with step-by-step Triol Wizard via smartphone, Service software Triol Drive for PC, Remote control panel with transient graphs
