Product Description:

The FVCA01.1-18K5-3P4-MDA-LP-P002-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat and supplied within the FVCA Frequency Converters series. Designed for three-phase industrial networks, it modulates voltage and frequency so that connected motors can accelerate, decelerate, or hold speed precisely under closed-loop or open-loop control in general automation lines. It is supplied in design revision 1.

Rated for an output of 18.5 kW, the converter delivers a continuous motor current of 39.0 A while operating from a nominal AC line of 400 V. The input side accepts 3 AC 380…480 V (-15 % / +10 %) across three phases and draws 48 A, producing 24 kVA of apparent power. A default carrier frequency of 6.0 kHz balances switching losses with acoustic noise. V/f, sensorless vector, and field-oriented control modes support either open-loop or encoder-based regulation, and commanded speed changes resolve to 0.01 Hz through the internal control electronics. Digital settings hold a tolerance of 0.01%, while analog reference signals remain within 0.05%. The frame D housing measures 440 mm high, 225 mm wide, and 227 mm deep, and the unit weighs 16.5 kg. An internal brake chopper is included, but an external resistor is required to dissipate regenerated energy.

The drive carries an IP 20 ingress rating for sheltered control cabinets used in industrial Class C3 environments. Thermal capability is maintained up to 1000 m above sea level, and above this point the converter follows a derating slope of 1%/100 m. Closed-loop operation offers a speed ratio of 1:1000 with an external encoder, while sensorless vector mode sustains 1:100. Parameterization can be performed through the front-panel LCD, the integrated potentiometer, or the RS-485-based Modbus interface. The unit also supports standard diagnostic, copy, and reload functions for parameter transfer.
