About product

Increased control accuracy

Variable Frequency Drive Triol AT24 line UС is an intelligent frequency drive for operating processes with high overload ability. There are all the advantages of Triol unique vector control algorithm implemented in Triol AT24 VFD line UC. Connecting three different types of encoders provides increased control accuracy to operate in a closed-loop system.

Easy set up

Setting up and controlling of Triol AT24 VFD line UC 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 terminal with transient graphs
