Product Description:

Bosch Rexroth Indramat manufactures the FVCA01.1-55K0-3P4-MDA-LP-NNNN-01V01 frequency converter within the FVCA Frequency Converters series. The unit provides variable-speed control for three-phase induction motors in automated lines, allowing process equipment to match motor torque and speed to load demands. It belongs to series line 01 and is delivered as design revision 1. Intended for wall-mounted installation, it uses an LCD panel and an onboard potentiometer for local adjustments, while Modbus enables remote parameter access from higher-level controllers. This arrangement supports both local setup at the unit and remote control through plant automation hardware.

During operation, the converter draws a three-phase supply within the 3 AC 380...480 V (-15 % / +10 %) window at a nominal voltage of 400 V. Its apparent power capability is 75.0 kVA, supporting a mechanical shaft output of 55.0 kW when the connected motor is at rated load. The input stage can handle 119.0 A, and the inverter delivers up to 110.0 A to the motor, so cable sizing and protective devices must cover those continuous currents. The default carrier frequency is 2.0 kHz, while field-oriented control keeps speed error within 0.05% of maximum frequency. Frame size F measures 325 mm wide and 265 mm deep, and relay outputs are rated 230 VAC or 30 VDC at 3 A for auxiliary signaling.

Thermal management relies on forced-air cooling, and the cabinet has an IP 20 rating for protected indoor locations. The drive stands 650 mm high and weighs 39.0 kg. Electromagnetic compatibility is supported by a Class C3 industrial filter, which helps reduce conducted interference on the supply side. An internal brake chopper is present, but it requires an external resistor for energy dissipation during fast deceleration. Operation is permitted up to 1000 m above sea level without current derating.
