Product Description:

The FVCA01.1-37K0-3P4-MDA-LP-P002-01V01 is a frequency converter produced by Bosch Rexroth Indramat as part of the FVCA Frequency Converters series. In automated plants, this unit modulates three-phase supply voltage to regulate induction or permanent-magnet motors, allowing speed control and energy savings across conveyors, pumps, and process machinery. Vector and scalar control modes, including V/f, SVC, and FOC, are selectable, and linear or S-curve ramps can be applied by the integrated PID regulator to shape acceleration and deceleration.

The unit has an output rating of 37.0 kW and an apparent input demand of 50.0 kVA, values that guide feeder sizing and cabinet thermal planning. Current delivery reaches 75.0 A at the motor terminals, matching applications that require high torque during continuous duty. The converter is intended for a three-phase mains supply centered on 400 V, permitting operation from 380 V to 480 V within the stated tolerance. For installation inside standard control enclosures, the unit carries an IP 20 protection rating that guards against finger contact while relying on cabinet airflow for dust exclusion.

Pulse patterns are generated at a 3.0 kHz carrier, balancing switching loss with acoustic noise, while the inverter adjusts output frequency in 0.01 Hz steps for precise speed trimming on slow conveyors. Closed-loop accuracy of 0.01% supports processes that cannot tolerate speed drift, and sensorless FOC startup delivers 200% torque at 0 Hz to help loaded machines overcome static friction before rotation begins. An LCD panel with a local potentiometer simplifies local adjustment, and Modbus connectivity links the unit to PLC networks. Mechanical dimensions of 525 mm in height, 250 mm in width, and 251.5 mm in depth are paired with a 22.0 kg mass for panel mounting in frame size E positions without additional bracing.
