Product Description:

The FVCA01.1-1K50-3P4-MDA-LP-NNNN-01V01 frequency converter is manufactured by Bosch Rexroth Indramat for the FVCA Frequency Converters series. Designed to modulate motor speed in automated production lines, the device provides vector or V/Hz control for standard induction machines and supports flexible speed regulation during normal process operation. It uses Frame Size A and measures 275 mm high, 125 mm wide, and 122 mm deep, with a net mass of 2.7 kg, so it fits compact cabinet layouts. A factory-integrated brake chopper routes regenerated energy to an external brake resistor so the drive can decelerate loads quickly during stopping.

The converter delivers 1.5 kW of mechanical output from a three-phase supply while operating on a nominal voltage of 400 V. Within the permitted three-phase input range, it draws 5.1 A at the input and supplies 4.0 A to the motor, yielding 2.6 kVA of apparent power. Analog setpoint tolerance is 0.05%, digital setpoint tolerance is 0.01%, and speed commands are resolved to 0.01 Hz. An LCD panel with an onboard potentiometer provides local control functions at the drive, and Modbus networking links the unit to higher-level controllers for remote data exchange. The enclosure carries an IP 20 rating and includes a Class C3 RFI filter, which supports installation in industrial switchgear and helps limit conducted interference.

Starting torque reaches 200% at 0 Hz, enabling loaded machines to overcome static friction, and closed-loop encoder feedback supports a 1:1000 speed range for low-speed regulation. Sinusoidal voltage is produced with an 8.0 kHz carrier using SVPWM, which helps reduce acoustic noise while maintaining smooth motor control. The permissible mains span of 3 AC 380…480 V (-15%/+10%) keeps the unit compatible with common plant feeders and allows operation across typical industrial supply variations.
