Product Description:

The FVCA01.1-18K5-3P4-MDA-LP-P001-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FVCA Frequency Converters series. It conditions three-phase power for induction and synchronous motors, supplying variable voltage and frequency so connected equipment can match speed and torque to process demands. By combining drive and control functions in one unit, it serves as a compact interface between plant mains and dynamic loads in automated lines.

The converter operates from a three-phase supply and uses a nominal DC link referenced to 400 V. It accepts 380 to 480 V AC input within a -15% to +10% tolerance range. At rated conditions, it delivers 18.5 kW of output power and supplies 39.0 A to the motor. Line demand reaches 48.0 A, which corresponds to 24.0 kVA of apparent power. A built-in potentiometer and PID regulator allow local adjustment, while analog commands track with 0.05% accuracy and digital setpoints resolve to 0.01%. Speed references step in 0.01 Hz increments, and sinusoidal SVPWM switching occurs at 6.0 kHz by default. Communication is handled through Modbus, and operating values are shown on an LCD interface. Frame size D construction includes a class C3 filter, and the internal brake chopper is ready for an external resistor. Under sensor vector control, the drive can deliver 150% torque at 0.5 Hz.

The housing is rated IP 20 and measures 225 mm wide, 227 mm deep, and 440 mm high. Its mass is 16.5 kg, which suits cabinet-mounted installations where space and support load matter. A dry-contact output rated at 230 VAC / 30 VDC / 3 A supports interlocking logic with external control circuits. In field-oriented mode, the drive can produce 200 % at 0 Hz starting torque, which improves low-speed load pickup and reduces the need to oversize the motor for standstill demand. The enclosure is intended for protected indoor installation, and the output contact provides a simple way to pass status or permissive signals to surrounding equipment.
