Product Description:

The FVCA01.1-45K0-3P4-MNA-LP-P001-01V01 is a frequency converter built by Bosch Rexroth Indramat for the FVCA Frequency Converters series. It links a three-phase mains supply to variable-speed induction or permanent-magnet motors, converting constant grid frequency into regulated voltage and frequency for pumps, conveyors, and other automated equipment. By supporting both V/f and vector control strategies, the device functions as an adjustable power stage that lets manufacturing lines match motor speed to process demand.

The converter delivers a continuous mechanical output of 45.0 kW, while the input section is rated for an apparent power of 62.0 kVA. Optimized for grids centered on 400 V, it can draw up to 104.0 A from the supply and deliver as much as 95.0 A to the motor terminals. One-second overload capability reaches 200% of nominal current, supported by a DC bus that tracks the mains at 1.41 × VAC. The F-size housing stands 650 mm high, 325 mm wide, and 265 mm deep, allowing straightforward panel installation in IP-rated control cabinets. An internal brake chopper is included, but an external resistor is required for energy dissipation during rapid deceleration.

Control functions include sensorless regulation across a 1:100 speed range and encoder-based vector control down to zero speed, where FOC supplies 200 % at 0 Hz starting torque. Insulated-gate devices switch at a default rate of 2.0 kHz using space-vector PWM, and the LCD interface allows frequency commands to be set with a resolution of 0.01 Hz. Communication over Modbus, along with a built-in potentiometer, provides local or network parameter adjustment. The enclosure carries an IP 20 rating for use in protected indoor areas, and the unit’s 37 kg mass aids thermal stability during continuous duty.
