Product Description:

The FVCA01.1-5K50-3P4-MDA-LP-NNNN-01V01 is a frequency converter from Bosch Rexroth Indramat and belongs to the FVCA Frequency Converters series. It conditions three-phase mains power and applies vector or scalar control algorithms to induction motors, allowing closed-loop speed control without separate PLC hardware. In automated lines, it bridges the fixed supply frequency and the variable mechanical demands of conveyors, pumps, or small process machines.

This unit is designed for a nominal bus of 400 V and delivers up to 5.5 kW of shaft power while drawing a rated line current of 16.5 A and providing a continuous motor phase current of 13.0 A. Its apparent power ceiling is 8.5 kVA, coordinated by a sinusoidal PWM stage that operates at a default carrier frequency of 8.0 kHz. U/f, SVC, and FOC modes share a freely adjustable V/f curve, and startup torque reaches 150% at 0.5 Hz in SVC or 150% at 5 Hz in U/f. The drive uses SVPWM modulation, supports frequency resolution down to 0.01 Hz, and holds digital setpoints within 0.01% tolerance. An integrated brake chopper pairs with an external resistor for controlled deceleration, and command inputs can be set from a front-panel potentiometer or through Modbus while parameters appear on an LCD display. Linear or S-curve ramps manage acceleration, and an industrial Class C3 filter limits conducted emissions.

The enclosure is rated IP 20, and the chassis weighs 4.9 kg with dimensions of 150 mm wide, 157 mm deep, and 330 mm high, which fit the B frame of the line. The converter accepts supplies from 3 AC 380…480 V (-15% / +10%) and can hold vector speed ratios of 1:100 without an encoder or 1:1000 with feedback. Field-oriented control can produce a stall torque of 200% at 0 Hz. The unit is in design revision 1 on series line 01, and its standard control package supports the available operating modes and ramp selection.
