Description
Lovato's VLB3 series of compact Variable speed Three Phase drives have three-phase supply input
- They are ideal for general applications and, in particular, to control and manage pumps and fans, thanks to several specific built in functions (S Curve, PID, torque squared control)
- They do not require any space for side ventilation, allowing installation of several side-by-side drives
- The user interface, which comprises of a built-in keyboard and display, allows to access the setting parameters easily, thanks to the use of extended texts describing the functions and codes
- Using the USB or Wi-Fi connection accessories, the programming, monitoring and diagnostics can be performed using a PC with software VLBX SW, downloadable from the website www.LovatoElectric.com
- The RS485 communication port with built-in modbus RTU (integrated in the complete drives VLB3... A480) and EMC filter complete the hardware supply
- The logic unit can be replaced with one of the VLBXL... codes, obtaining a communication port with different protocol
