Product Description:

The FVCA01.2-2K20-3P4-MDA-LP-NNNN-02VRS frequency converter is produced by Bosch Rexroth Indramat and belongs to the FVCA Frequency Converters series. It is intended for speed and torque control of three-phase induction or synchronous motors in automated machinery and process equipment. By converting fixed mains input into a variable amplitude and frequency output, the unit enables energy-efficient adjustment of fan, pump, and conveyor drives within industrial automation cells. This lets connected motors respond to changing process demands without fixed-speed operation.

As revision 2 in the 01 series line, this converter accepts a three-phase supply at a nominal 400 V level across a 3 AC 380–480 V tolerance band and presents 3.6 kVA of apparent power to the DC link. Switching devices are triggered at a carrier frequency of 8.0 kHz, and the output frequency can be adjusted in 0.01 Hz steps because of the high digital resolution. Vector and scalar regulation modes, including U/f, SVC, and FOC, are supported, and modulation is performed by SVPWM with a preconfigured PID controller for closed-loop tasks. Class C3 filtering permits installation in industrial environments, while the enclosure carries an IP 20 rating. Mechanical dimensions are 275 × 125 × 122 mm (H × W × D), frame size A, and an integrated brake chopper can be paired with an external resistor when dynamic stopping is required.

The power stage delivers 2.2 kW continuously and draws up to 7.6 A, forwarding 5.5 A to the motor. A form-C relay rated 230 VAC or 30 VDC at 3 A supplies status or fault outputs to higher-level controllers, and it can be used for run indication or fault signaling in supervisory control circuits. Modbus networking, an LCD panel, and an onboard potentiometer simplify local or remote adjustment. Handling is straightforward because the unit weighs only 2.8 kg.
