Product Description:
The FVCA01.2-4K00-3P4-MDA-LP-NNNN-02VRS is a member of the FVCA Frequency Converters series produced by Bosch Rexroth Indramat. As a variable-speed drive, it converts fixed three-phase mains into a regulated frequency and voltage output so induction or synchronous machines can be matched to process demands. The unit supports V/f scalar control, sensorless vector control, and field-oriented control through space-vector PWM, allowing deployment in assembly lines, material-handling conveyors, and HVAC fans where consistent torque at low speed is required.
It delivers an apparent power of 6.5 kVA and accepts a nominal input of 400 V, operating within a 3 AC 380 to 480 V supply window with a -15% to +10% tolerance. The inverter can provide up to 4.0 kW of output power and draws 16 A on the line side. Switching devices operate at a factory-set carrier of 8.0 kHz, balancing acoustic performance and thermal load. Frequency references from the keypad, ModBus, or the onboard potentiometer are resolved to 0.01 Hz, enabling fine speed trimming during closed-loop PID operation. A built-in brake chopper works with an external resistor for rapid deceleration, and the Class C3 input filter limits conducted emissions. The B-frame housing measures 150 mm by 157 mm by 330 mm and mounts with four M6 screws.
At cold start, the field-oriented algorithm can generate torque of 200% at 0 Hz, letting lifting or tensioning axes move without a gearbox. When an analog speed command is used, regulation holds within 0.05%, supporting precise web handling or metering pumps. The power stage feeds the output terminals and energizes a form-C relay rated at 230 VAC / 30 VDC / 3 A for status signaling to external safety interlocks. Advanced SVPWM, autotuning, and multi-level protection functions are available through the LCD menu.
