Product Description:

The FVCA01.1-90K0-3P4-MDA-LP-NNNN-01V01 is a three-phase frequency converter from Bosch Rexroth Indramat in the FVCA Frequency Converters series. It provides variable speed control for industrial pumps, fans, and material-handling drives by switching between V/f, sensorless vector, and field-oriented control modes to suit the attached motor. A front-panel potentiometer allows local reference adjustment, while an LCD display and a ModBus interface present operating data and allow remote parameterization through supervisory control networks. This arrangement supports both standalone operation at the drive and monitored operation from a higher-level control system.

The inverter supplies 90.0 kW of mechanical output while drawing up to 116.0 kVA from the mains and a steady 184.0 A of line current under nominal loading. It accepts three-phase input power at 50 or 60 Hz on a nominal 400 V supply and, through space-vector modulation, produces motor frequencies from 0 to 400 Hz. The carrier is fixed at 2.0 kHz, balancing switching loss with acoustic performance. Closed-loop commands are resolved to 0.01% through the digital setpoint path, and the rated output current reaches 176 A. An external resistor can be connected to the built-in chopper for regenerative braking, and the Class C3 filter helps limit conducted emissions in industrial plants.

A short overload capability of 200% In for 1 s accommodates high-inertia starts before thermal derating begins at 1000 m altitude. The converter weighs 58.0 kg, is assigned frame size G, and measures 700 mm high, 450 mm wide, and 302.5 mm deep for vertical mounting. Incoming power must remain within 3 AC 380…480 V (-15 % / +10 %), and the enclosure has an IP 20 rating, so the unit should be installed in a clean, enclosed panel with relative humidity below 90%.
