When a motor-driven machine needs controlled speed, torque, acceleration, and stopping, connecting the motor directly to a fixed-frequency supply can limit how precisely the equipment can operate. A variable frequency drive provides adjustable motor control while also offering communication, PLC, braking, monitoring, and protection functions within the drive.
Beijer BFI-P2-44-0460-3F4N-MN, IP55 AC variable frequency Drive
The Beijer BFI-P2-44-0460-3F4N-MN is an IP55 AC variable frequency drive designed to control three-phase AC motors with a rated motor current of 46 A and motor power of 22 kW. It converts the incoming 380–480VAC supply into controlled motor output, allowing motor speed and operating behavior to be adjusted according to the application.
The drive supports several motor types, including three phase AC induction (IM), AC permanent magnet (PM), Brushless DC (BLDC), and Synchronous reluctance (SynRM). Its control modes include V/F Voltage Vector, Sensorless Vector Speed Control, Sensorless Vector Torque Control, Closed Loop Speed Control, Closed Loop Torque Control, and other specified motor control methods, providing different approaches for controlling motor operation.
For applications where acceleration, stopping, and braking need to be managed, the drive provides adjustable ramp-to-stop, fast stop, coast-to-stop, motor flux braking, and a built-in braking transistor. Torque and current limitation, skip frequency, and adjustable PWM frequency further support controlled motor operation. The drive can also provide regenerative capacity at 100 % ED.
The BFI-P2-44-0460-3F4N-MN includes Modbus RTU and CANopen communication, while several industrial Ethernet and fieldbus protocols are available as external options. Its digital and analog setpoint options allow speed or control references to be supplied through voltage, current, fixed speeds, motorised potentiometer, internal PLC, keypad, and supported communication interfaces.
The IP55 enclosure is designed for installations where protection from dust and water is required. The drive also includes a built-in PLC, master/slave speed control, advanced hoist control, PID control with sleep/wake functionality, programmable display, safety inputs, Safe Torque OFF, fault memory, data logging, and service-life monitoring. CE, UL, cUL, DNV, and the specified safety and compliance standards support its use in industrial and marine applications.
