Product Description:

The FVCA01.2-75K0-3P4-MDA-LP-NNNN-02VRS belongs to the FVCA Frequency Converters series from Bosch Rexroth Indramat. It is a cabinet-mounted AC frequency converter that rectifies fixed mains power and creates an adjustable output for three-phase motors used on conveyors, pumps, and general process machinery. By using closed-loop current regulation and vector control inside the drive, it removes the need for external starters and lets the system match motor speed and torque to changing load demands. This control method helps the drive respond smoothly during acceleration, deceleration, and varying process demand.

Electrically, the converter is rated for 100 kVA of apparent power and 75 kW of motor output. It accepts a three-phase supply of 380 to 480 V AC with a tolerance of -15% to +10% and stabilizes operation around a nominal bus of 400 V. The line side draws 157 A, and the inverter supplies 152 A under rated load. SVPWM modulation, a PID regulator, and field-oriented control support 200% startup torque at 0 Hz. A Modbus port enables remote parameter access, and 0.01% digital setting accuracy supports fine adjustment. The Class C3 filter helps reduce conducted electrical noise on the supply connection. When regenerative braking occurs, an external resistor is required for the internal brake chopper to dissipate excess energy.

The G-frame housing is 700 mm high, 450 mm wide, and 302.5 mm deep, weighs 56.7 kg, and has an IP20 enclosure rating for protected indoor panels. Its cabinet-mounted form is intended for enclosed installations rather than exposed machine surfaces. The product is Series Line 01 with hardware revision 2. An LCD interface and an integral potentiometer allow local adjustments while network control remains available. The inverter's carrier frequency defaults to 2 kHz, and commands are executed with a resolution of 0.01 Hz.
