Product Description:

The FVCA01.1-5K50-3P4-MDA-LP-P002-01V01 frequency converter is built by Bosch Rexroth Indramat for the FVCA Frequency Converters series. It converts fixed three-phase mains power into a variable output for speed control of induction motors in automated material-handling or process lines. Local control is provided through an LCD display and a rotary potentiometer, while an integrated brake chopper safely dissipates regenerated energy. This arrangement allows basic speed adjustment at the drive without requiring a separate operator panel. The frame size B unit is intended for wall mounting with M6 hardware, and it weighs 4.9 kg.

The drive supplies 5.5 kW of motor power from a nominal bus of 400 V and accepts a supply range of 3 AC 380...480 V (-15% / +10%), matching standard three-phase plant feeds. The unit draws 16.5 A from the line and delivers 13.0 A at the output. The default carrier frequency of 8.0 kHz sets the IGBT switching rate, balancing acoustic noise with thermal stress. Forced-air cooling moves heat through the 150 mm wide, 157 mm deep, and 330 mm high enclosure. A Class C3 EMC filter reduces conducted emissions. Rated values apply up to 1000 m above sea level, and above this altitude the power is derated by 1% for every additional 100 m. The unit operates below 90% relative humidity and withstands shocks below 5.9 m/s².

Peak apparent demand reaches 8.5 kVA, so upstream protection devices must be sized accordingly. Remote supervision uses Modbus networking, which allows parameter access without extra I/O wiring. An IP 20 housing provides finger-safe protection, but it requires installation inside a cabinet for dust or splash protection. This cabinet requirement is important in areas where airborne dust or liquid splash may be present. The three-phase supply connects to internally threaded M6 terminals.
