Product Description:

The Bosch Rexroth Indramat FVCA01.1-37K0-3P4-MNA-LP-NNNN-01V01 is a wall-mounted frequency converter in the FVCA Frequency Converters series. Release number 01 and series line 01 identify its production baseline, and design revision 1 indicates a standard build. The unit accepts three-phase industrial mains in the 3 AC 380 to 480 V range to regulate motor speed for pumps, fans, and material-handling axes. Its frame size E enclosure measures 525 mm in height, 250 mm in width, and 251.5 mm in depth, and it includes an LCD interface with an integrated potentiometer for local setup.

The converter delivers 37.0 kW of rated output power at 75.0 A of output current while drawing 88.0 A from the line. It matches motors through space-vector PWM at a default switching rate of 3.0 kHz. Frequency commands entered over ModBus or the onboard knob are processed with a digital resolution of 0.01 Hz and a setpoint tolerance of 0.01%, which supports fine speed trimming. No EMC input filter is fitted, and the converter supports a 1:1000 vector control range with SVPWM modulation for quiet operation. An external resistor must be connected to the internal brake chopper to absorb regenerative energy, and an overload capacity of 200% of rated current for one second helps the drive handle process surges.

During closed-loop operation, the field-oriented controller holds speed within 0.05 % x Max Freq. It can generate starting torque of 200 % at 0 Hz for heavy loads. The converter supplies motors at a nominal voltage of 400 V and reaches up to 50.0 kVA of apparent power while remaining within the IP20 enclosure class. A net mass of 22.0 kg supports cabinet installation, and reliable service is maintained up to 1000 m altitude without derating. This model is intended for vector-controlled drives that need precise speed hold and rapid braking.
