Product Description:

The FVCA01.2-5K50-3P4-MDA-LP-NNNN-02VRS is a frequency converter from Bosch Rexroth Indramat in the FVCA Frequency Converters series. It controls the speed of three-phase induction motors by supplying variable voltage and frequency. This supports closed-loop or sensorless regulation in industrial automation tasks that require accurate torque control and efficient energy use. By adjusting output to match process demand, it avoids fixed-speed operation and improves flexibility in motor-driven systems.

The drive has a rated output of 5.5 kW and an apparent input of 8.5 kVA. It is built for three-phase power systems and accepts a nominal line voltage of 400 V within a 380 to 480 V range, with a rated input current of 16.5 A; under rated conditions, the motor output current is 13.0 A. Available control methods include V/f, sensor-vector control, and field-oriented control with an internal PID loop, while SVPWM modulation runs at a default carrier frequency of 8.0 kHz. The interface provides 0.01 Hz digital frequency resolution, 0.05% analog setting accuracy, and Modbus communication for remote commands. Under field-oriented control, the converter can provide 200% startup torque at 0 Hz and uses an integrated brake chopper with an external resistor for dynamic braking.

For intermittent overload, the unit can withstand 200 % In for 1 s, which supports rapid acceleration of high-inertia loads. The housing is rated IP 20, uses Industrial Class C3 EMC filtering, and is suitable for operation up to 1000 m altitude. The converter uses Frame B construction and has a width of 150 mm, a depth of 157 mm, a height of 330 mm, and a mass of 4.9 kg. An LCD panel and onboard potentiometer allow local adjustment, while encoder feedback supports a 1:1000 range and sensorless regulation supports 1:100. The unit is design revision 2 in series line 01.
