Product Description:

The FVCA01.1-55K0-3P4-MDA-LP-P002-01V01 frequency converter is produced by Bosch Rexroth Indramat for the FVCA Frequency Converters series. Acting as a variable-speed AC drive, it converts three-phase supply power into controlled output for induction motors used in conveyors, pumps, and ventilation systems. This allows connected equipment to run at speeds that better match process demand instead of operating only at fixed line frequency. The unit is intended for industrial automation duties where stable motor control, straightforward parameter access, and standard field communication are required.

The unit is rated for an apparent power of 75.0 kVA, and its continuous motor output is 55.0 kW. The rectifier draws a rated input current of 119.0 A, while the inverter supplies 110.0 A to the motor. An external braking resistor is required because the internal brake chopper is intended for that connection. The converter operates from a three-phase network, communicates over ModBus, and includes a front-panel potentiometer for local speed reference. Operating status and parameter data are shown on an LCD, and a Class C3 EMC filter is integrated to help limit conducted emissions in industrial installations.

Thermal control relies on forced-air cooling, so the installation must allow space for airflow through the cabinet. The inverter has a nominal bus voltage of 400 V and operates over an input range of 3 AC 380…480 V (-15 % / +10 %). Its default carrier frequency is 2.0 kHz, and the enclosure is rated IP20 for wall mounting inside a control panel. The mechanical layout follows frame size F, with a width of 325 mm, a depth of 265 mm, a height of 650 mm, and a net weight of 39 kg. The brake circuit is prepared for an external resistor, and the hardware supports EMC-compliant wiring practices.
