Three-phase inverter for motor control

This three-phase inverter, with a supply voltage of 3x400V AC and an input current of 16.5A, is a reliable solution for precise motor control. Designed for both professional installers and end-users, it offers wide configuration possibilities and ensures optimal performance in various industrial applications. The maximum power output reaches 5.5kW, making it suitable for a variety of loads.

Construction and functionality

The inverter is based on an efficient 32-bit DSP processor, which guarantees fast and effective operation of advanced control algorithms. The ability to operate in speed or torque control mode allows adaptation to specific application requirements. Motor control is performed via vector control – both sensorless and with speed feedback – as well as based on programmable V/F characteristics. The built-in Modbus RTU (RS485) interface enables easy integration with industrial automation systems and remote control and monitoring of the device.

Applications and benefits

The inverter finds application in a wide range of industrial applications, such as:

• Pumps and fans: Precise speed control allows for optimizing energy consumption and adapting performance to current needs.
• Conveyors: Smooth start and stop minimize mechanical loads and extend the life of equipment.
• Packaging machines: Accurate motion control ensures high precision and repeatability of processes.
• Compressors: Optimizing compressor operation allows for energy savings and reduced operating costs.
• Dosers: Precise control of substance dispensing ensures accuracy and efficiency of production processes.

Additional functions, such as automatic slip compensation and high torque (up to 180% at 0.25Hz), ensure reliable operation even in difficult conditions. A multifunctional control panel with the ability to store up to four sets of parameters facilitates configuration and servicing of the device. PLC mode allows programming of operation sequences, increasing the flexibility of inverter applications. Protection class IP20 provides protection against touch and contamination.
