Product Description:

The FVCA01.1-0K40-3P4-MDA-LP-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FVCA Frequency Converters series. As a variable-speed AC drive, it modulates three-phase line power to regulate induction or synchronous motors in automated machinery and material-handling systems. The unit provides voltage and frequency control, torque boosting, and braking management so motor speed can be matched to process demands. This makes it suitable for conveyors, pumps, and similar equipment that needs adjustable speed from a standard industrial power source.

Its motor output is rated at 0.4 kW, and the converter operates from a three-phase supply rated at 400 V. Under nominal conditions, the line current is limited to 1.6 A, which helps keep upstream protection requirements modest. A carrier using the default 8 kHz SVPWM pattern, together with U/f, sensorless vector, and field-oriented control modes, supports smooth regulation up to 400 Hz output frequency. Frequency settings can be adjusted in 0.01 Hz increments with a digital setting accuracy of 0.01%, and changes can be entered with the front-panel potentiometer, the LCD keypad, or through a Modbus interface. The integrated brake chopper supports an external resistor for controlled deceleration.

An apparent power requirement of 0.8 kVA keeps input demand relatively low, and the compact A-frame housing measures 275 mm high, 125 mm wide, and 122 mm deep with a mass of only 2.7 kg. The IP20 enclosure provides touch protection inside control cabinets, while the built-in C3 filter reduces conducted emissions in industrial installations. Field-oriented control can produce up to 200% starting torque at 0 Hz, which helps the drive start heavy loads without an encoder. When encoder feedback is added, the speed range can extend to 1:1000 for applications that need wider speed control.
