Product Description:

The FVCA01.1-75K0-3P4-MDA-LP-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FVCA Frequency Converters series. The unit conditions three-phase utility power and generates variable-frequency output that allows automated lines to adjust motor speed, reduce energy use, and synchronize motion in material-handling or process equipment. It installs in control cabinets where stable motor regulation and controlled power conversion are required. This makes it suitable for conveyors, pumps, fans, and other variable-speed applications that benefit from controlled acceleration and deceleration.

In operation, the converter delivers 75.0 kW output power while supporting an apparent load of 100.0 kVA. Its input range is 3 AC 380 to 480 V (-15% / +10%), with a 400 V nominal voltage that suits common industrial feeders. At full load, it draws 157.0 A of rated input current and supplies 152.0 A of rated output current through space-vector PWM at 2.0 kHz. SVPWM, together with a speed control ratio of 1:100 and an encoder speed ratio of 1:1000, supports stable torque across the operating range. The forced-air cooling design also includes a brake chopper that requires an external resistor to absorb regenerated energy during rapid stops.

Parameter accuracy is supported by an analog set tolerance of 0.05 %, a digital set tolerance of 0.01 %, and a frequency step resolution of 0.01 Hz. Local adjustments are made with the built-in potentiometer and LCD display, while Modbus links the device to higher-level PLCs for command and monitoring functions. Class C3 filtering and IP20 protection support use in enclosed industrial cabinets. The frame size G housing measures 700 mm high, 450 mm wide, and 302.5 mm deep, and it weighs 56.7 kg. An M10 screw set and a 5.9 m/s² shock limit help the converter remain secure during normal machine vibration.
