The VACON 20 Low Voltage Drives series is a compact AC drive platform designed for fixed industrial installations, with available versions for 115 V, 208–240 V, 380–480 V, and 600 V supply systems in single-phase or three-phase configurations depending on the model.
The series supports a broad range of motor-control and application functions, including programmable start and stop logic, adjustable ramps and braking behavior, PID control, motor pre-heat, prohibited frequency settings, automatic fault reset, and fieldbus data mapping. Its standard control architecture includes six digital inputs, two analog inputs, one analog output, one digital output, two relay outputs, and an RS-485 interface, while optional boards add communication choices such as EtherCAT, PROFIBUS DP, CANopen, DeviceNet, Modbus TCP, and PROFINET. The platform is also built for installation flexibility, with DIN-rail or screw mounting on smaller frames, flange or screw mounting on larger frames, compact IP20 or IP21/NEMA 1 enclosure formats, and selectable EMC configurations depending on the application environment. Across the range, the VACON 20 series is positioned as a low-voltage variable frequency drive family for general motor control and HVAC-related use, with frame sizes spanning compact low-power units up to larger models with optional brake-resistor connections and expanded cooling requirements.
