Product Description:

Bosch Rexroth Indramat manufactures the FVCA01.1-15K0-3P4-MNA-LP-NNNN-01V01, a frequency converter in the FVCA Frequency Converters series for speed regulation of three-phase induction or synchronous motors in automated lines. Communication is provided through a ModBus port, while a built-in potentiometer offers local set-point control and an LCD presents operating data. Hardware details include frame size C, a width of 175 mm, height of 398 mm, and depth of 199 mm, with a net mass of 9.0 kg. Design revision 1 in series line 01 is shipped with the standard full-version firmware (version 01); there is no special design variant and no line-side filter. SVPWM modulation, an integrated brake chopper, and a field-oriented control accuracy of 0.05 % × fmax complete the drive-side electronics.

Electrical ratings specify how the unit connects to the mains and the load. It accepts three phases in a 3 AC 380…480 V window and delivers a nominal output of 400 V. Rated mechanical output is 15.0 kW, derived from an apparent input of 21.0 kVA. Motor current reaches 33.0 A while the supply draws 46 A. Carrier generation uses a default switching frequency of 6.0 kHz, balancing acoustic performance and thermal stress. Closed-loop operation with an encoder preserves speed over a 1:1000 range, and the voltage tolerance (-15 %/+10 %) allows continued service on weak or fluctuating grids.

Additional capabilities support demanding duty cycles and enclosure integration. A short-time overload of 200% In for 1 s handles acceleration bursts, and field-oriented control produces 200% at 0 Hz start-up torque for break-away loads. Frequency can be trimmed in steps of 0.01 Hz, beneficial for slow-speed process zones, while the housing carries a protection rating of IP 20 for mounting within control cabinets. Continuous operation is specified up to 1000 m altitude with relative humidity below 90 %, and no external filter is needed because the design already meets the stated electromagnetic requirements.
