Product Description:

The FVCA01.1-37K0-3P4-MDA-LP-NNNN-01V01 is an AC drive produced by Bosch Rexroth Indramat for the FVCA Frequency Converters series. Delivered in frame size E and design revision 1, the converter belongs to release number 01 of series line 01. It converts a three-phase 400 V supply into a variable-frequency output so that asynchronous or permanent-magnet motors can be speed controlled in factory cells. The housing measures 525 mm in height, 250 mm in width, and 251.5 mm in depth, and it weighs 22.0 kg. This cabinet-mounted unit is intended for finger-safe areas and provides front access to an LCD keypad and a built-in potentiometer.

Electrical capacity centers on 37.0 kW of continuous mechanical power, delivered at a rated motor current of 75.0 A when the mains stays within the 380 to 480 V range. The analog reference channel maintains speed accuracy within 0.05 %, and digital frequency steps are as fine as 0.01 Hz. An overall digital setpoint accuracy of 0.01% is maintained, allowing U/f, sensorless vector, and field-oriented modes to operate with the same control structure. A carrier frequency of 3.0 kHz is generated by the SVPWM modulator, while the line side draws 88 A from the three-phase supply. Modbus networking, a local display, a standard full software edition, and a brake chopper terminal for an external resistor support local setup and regenerative operation.

Field-oriented startup delivers 200 % at 0 Hz torque, so loaded conveyors or presses can begin moving immediately. Once rotating, the speed range extends from 1:100 without feedback to 1:1000 with an encoder. Upstream protection must accommodate 50.0 kVA of apparent power, and conducted-emission compliance is achieved with the industrial filter rating Class C3. The finger-safe housing meets IP20 for indoor enclosure mounting. Additional configuration data are stored in the integrated memory and can be retrieved through the same communication port used for setup.
