Description
Lovato VLA122A240
VLA1 is a compact size drive with high performance. It integrates different motor control modes, such as linear and quadratic V/f and sensorless vector control. It is versatile and can be used in multiple applications such as the management of automatic doors, assembly machines, packaging machines, packaging machines, conveyor belts and in particular for the management of pumps and fans thanks to specific functions such as PID control and on-the-fly speed search . Easy to install and program. The user interface, consisting of a keypad and display mounted on board, allows access to the configuration parameters in an intuitive way thanks to the use of extended texts to describe the functions. Furthermore, with the USB communication module, programming, monitoring and diagnostics can be done via PC with the VLBXSW software, downloadable from the www.LovatoElectric.com website. SPEED REFERENCE SIGNALS: The reference signals for speed regulation occur via: – external potentiometer 0..10kΩ, – analogue voltage signals 0..10VDC or current 0/4..20mA, – buttons on the front keyboard, – door mounting kit, – 15 speeds selectable with digital inputs, – motorized potentiometer. PROGRAMMABLE INPUTS AND OUTPUTS: – selectable pNp or nPn connection, – 5 digital inputs, – 1 digital output, 1 changeover relay output, – 2 analogue inputs: • 1 in voltage 0...10VDC • 1 configurable in voltage 0. ..10VDC or in current 0/4..20mA, – 1 analogue output configurable in voltage 0..10VDC or in current 0/4..20mA. PROTECTIONS: – overcurrent, – output and earth short circuit, – overvoltage, – undervoltage, – phase failure, – motor thermal overload (i2t), – overspeed, – speed reversal.
