VLA1 Variable Speed Drives Single Phase Drives by Lovato

Description

Lovato's VLA1 series of ultra-compact Variable speed Single Phase drives offer high performance

• They integrate different motor control modes, like V/f linear and quadratic and sensorless vector control
• VLA1's are extremely versatile and can be used in several applications such as conveyor belts, machine tools, control of automatic doors, packaging machines and in particular to manage pumps and fans thanks to specific integrated functions like the PID control and flying restart
• Simple to install and configure
• The user interface, which comprises of a built-in keypad and display, allows to access the setting parameters easily, thanks to the use of extended texts describing the functions and codes
• Using the optional USB communication module, the programming, monitoring and diagnostic can be performed using a PC with software VLBXSW, downloadable from the website www.LovatoElectric.com
