Frequency inverter

With CANopen and Devicenet

The S2U by Bonfiglioli is an IP66-rated inverter series. It is particularly suited to harsh habitat applications. The heat sink is specially designed for extreme environmental conditions such as dust, humidity, and cleaning chemicals.

The plug-and-play inverter’s features include a 32-bit processor with advanced IGBT power switching. Built-in PID controller and PLC functions control frequency, pressure, and air volume, for instance for heating, ventilation, and air-conditioning applications. The built-in EMC filter in compliance with IEC/EN61800-3 ensures low electromagnetic interference, enabling safe usage, said the company. Additional features of the series include slip and torque compensation and an emergency stop function. A carrier frequency of 1 kHz to 16 kHz which automatically changes according to the temperature function, an integrated braking chopper, as well as a special fire mode function for fan applications are also provided.

The keypad on the front panel of the inverter facilitates set-up and operation for the user. Thanks to an integrated logic function such as mathematical operators and Ladder programming language, which is compatible with IEC 61131, the inverter can be individually adapted without the need for a PLC. Moreover, they support a broad range of communication interfaces including for CANopen and Devicenet. The product comes in a temperature-optimized and an IP20-rated enclosure. It provides one analog input, five digital inputs, one analog output, and one relay output.

The frequency inverter can be adapted to a wide range of applications such as pumps, fans, smart conveyors, textile, material handlings, wood processing as well as food and beverage.
