Product Description:

The FVCA01.1-4K00-3P4-MDA-LP-P002-01V01 frequency converter from Bosch Rexroth Indramat is part of the FVCA Frequency Converters series. In automated lines, it regulates induction motor speed by varying stator frequency and voltage, allowing conveyors, mixers, or fans to match process demands while maintaining efficiency. The unit integrates drive, control, and diagnostic functions into a compact frame that mounts inside a standard control cabinet. This arrangement supports variable-speed operation without requiring a separate standalone speed-control device for normal use.

Its nominal supply is 400 V, three-phase, within a tolerance of −15% to +10%, so the converter can be wired directly to typical plant power without an isolation transformer. Under full load, the drive draws 16.0 A and delivers 4.0 kW of mechanical output, values that guide cable sizing and breaker selection. The default carrier of 8.0 kHz sets the switching pattern for the SVPWM modulator, balancing acoustic noise and thermal loss. For closed-loop speed control, the PID regulator works with a frequency adjustment resolution of 0.01 Hz, giving fine incremental changes when coordinating multiple driven sections in the same process.

The apparent power reaches 6.5 kVA, indicating the reactive demand the upstream supply must handle during dynamic loading. An enclosure rating of IP 20 suits protected indoor panels while still allowing natural air convection over the heat sink. When process demands exceed base speed, the converter can extend output up to 400 Hz, enabling high-speed motor operation within the intended control range. The housing dimensions of 150 mm × 330 mm × 157 mm help conserve cabinet space, and a net mass of 4.8 kg supports straightforward panel mounting with standard M6 screws. Space must still be reserved in the cabinet for the required external braking resistor and line filter.
