Product Description:

The FVCA01.2-22K0-3P4-MDA-LP-NNNN-02VRS frequency converter is produced by Bosch Rexroth Indramat and belongs to the FVCA Frequency Converters series. The device is intended for motor speed control in industrial automation, receiving three-phase power and generating a variable AC output through space-vector PWM so that connected machinery can match process demand. Its integrated PID controller and built-in potentiometer permit stand-alone adjustment, while the ModBus interface allows higher-level PLC supervision.

During operation the drive delivers 22.0 kW of mechanical output, supported by an apparent power handling of 30.0 kVA at the input terminals. It draws up to 53.0 A from the supply and can return 44.0 A to the motor windings. The acceptable line window is 3 AC 380...480 V (-15 % / +10 %) with a 400 V nominal reference, enabling direct connection to common plant feeders. Carrier switching is preset to 6.0 kHz, balancing electromagnetic loss and audible noise. Field-oriented control can produce 200 % start-up torque at 0 Hz, and the internal chopper is prepared for an external brake resistor to dissipate regenerated energy. Supply enters through three phases, modulation follows SVPWM, and filtering is rated for industrial C3 environments.

Control resources include 4 analog inputs, 10 digital inputs, 1 encoder channel, and 2 relay outputs, each set via the LCD display with 0.01 Hz frequency resolution. Communication relies on ModBus RTU; hardware revision is 2, series line 01, and no design variant is assigned. Standard full-version firmware ships in the latest release state, and frame size D is specified. Mechanical data list a protection score of IP 20, a height of 440 mm, and a net mass of 16.5 kg; width is 225 mm and depth is 227 mm, secured to the panel with M8 screws.
