Product Description:

The FVCA01.1-55K0-3P4-MNA-LP-P001-01V01 is a frequency converter built by Bosch Rexroth Indramat for the FVCA Frequency Converters series. It accepts three-phase 380 to 480 V AC mains and delivers variable voltage and frequency for speed control of induction or permanent-magnet motors in industrial automation. The unit is in frame size F, uses design revision 1 with release number 01, and includes a front-panel potentiometer for manual setpoint entry. This arrangement allows local adjustment without requiring a separate external reference source.

The drive is rated for motor output of 55.0 kW and draws an apparent input power of 75.0 kVA. Its rated input current is 119.0 A, and the inverter can supply 110.0 A to the motor over an output frequency range of 0 to 400 Hz. The converter uses a nominal 400 V bus, and the rectified DC link follows the mains voltage by a factor of 1.41. It supports U/f, SVC, and FOC control modes, while SVPWM switching is applied with a default carrier frequency of 2.0 kHz. Communication is handled through a Modbus interface, and operating values are shown on an LCD. No internal line filter is installed, and an external brake resistor is required because the brake chopper is present only as a switching element. The overload capability is rated at 200% In/1 s; 150% In/60 s, and the supply frequency tolerance is 50 to 60 Hz with a variation of plus or minus 5 percent.

The housing is 325 mm wide, 265 mm deep, and 650 mm high, with a net mass of 39 kg. The enclosure has an IP 20 rating, so it is intended for protected switch-cabinet installation rather than open or washdown areas. Relative humidity should remain below 90 percent during operation, and additional enclosure protection is needed where splash or direct dust exposure is possible. These dimensions fit cabinet layouts that need a high-power converter in a controlled indoor environment.
