Product Description:

The FVCA01.1-22K0-3P4-MDA-LP-NNNN-01V01 is a variable-frequency drive manufactured by Bosch Rexroth Indramat for the FVCA Frequency Converters series. It converts fixed three-phase mains power into a controlled output waveform so AC motors can start, stop, and vary speed without mechanical ratio changes. This makes the unit suitable for automated machinery that needs adjustable motor control through either open-loop or closed-loop operation. Typical uses include conveyors, process equipment, and spindle-driven machines that need stable speed control under changing load conditions.

This wall-mount drive accepts a three-phase supply of 3 AC 380…480 V. It provides up to 22.0 kW of motor power and can draw a peak apparent power of 30.0 kVA. The output stage delivers a continuous motor current of 44.0 A, and the operating frequency range extends to 400 Hz with a resolution of 0.01 Hz. Vector control supports start-up torque of 200% at 0 Hz, while the speed control range reaches 1:100 in open-loop mode and 1:1000 when encoder feedback is used. PWM switching uses a 6 kHz carrier as the default minimum setting, and output derating begins above that value. ModBus communication, an LCD display, and an on-panel potentiometer are included for control and parameter access.

The enclosure is rated IP20, which helps protect internal parts from contact with solid objects larger than 12.5 mm. Forced-air cooling is used to manage internal heat, and the internal brake chopper requires an external resistor so regenerative energy can be dissipated outside the drive. The frame D housing measures 440 mm × 225 mm × 227 mm and has a mass of 16.5 kg. Its wall-mount format supports direct panel installation, and operation is permitted at altitudes up to 1000 m. An integrated Class C3 RFI filter is included for industrial power systems.
