Product Description:

The FVCA01.1-45K0-3P4-MDA-LP-NNNN-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat for the FVCA Frequency Converters series. As a three-phase AC unit for 400 V mains, it supplies variable frequency to induction or permanent-magnet motors in automated production lines. The converter supports V/f, SVC, and FOC control modes for compatibility with different torque and speed profiles. The unit includes an integral potentiometer for local setpoint entry and an LCD display for status indication.

The electrical envelope starts with a permissible mains window of 3 AC 380...480 V (-15 % / +10 %), which yields a DC bus of approximately 1.41 times the phase voltage. Under nominal load, the converter draws 104.0 A and supplies 95.0 A, enabling a continuous shaft output of 45.0 kW from an apparent base of 62.0 kVA. Analog references are accepted with 0.05% tolerance, digital commands with 0.01%, and the resulting frequency can be set in 0.01 Hz steps. Modbus links the controller to higher-level PLCs, while an SVPWM bridge handles power switching and an internal chopper directs regenerative energy to an external resistor.

The unit is delivered in frame size F with overall dimensions of 650 mm in height, 325 mm in width, and 265 mm in depth, and it weighs 37.0 kg. Cooling air passes through an IP 20 housing, a rating that blocks finger access while allowing panel ventilation in switchgear rooms that match the drive’s Industrial Class C3 EMC filter. The power stage switches at a carrier frequency of 2.0 kHz and can generate 200% at 0 Hz startup torque when FOC mode is selected, helping heavy loads break away from standstill. This model is identified as design revision 1 within series line 01 and release state 01.
