Product Description:

The FVCA01.1-75K0-3P4-MDA-LP-P002-01V01 frequency converter is manufactured by Bosch Rexroth Indramat for the FVCA Frequency Converters series. It is intended for three-phase mains and converts fixed line power into variable frequency and voltage so induction or synchronous motors can match changing load demands in automated production and material-handling equipment. By regulating motor speed electrically instead of relying on mechanical throttling methods, the unit can reduce energy use and help limit heat buildup in connected systems. This makes it suitable for applications that need controlled acceleration, stable running speed, and repeatable motor response.

Power delivery reaches 75.0 kW of continuous mechanical output, supported by an apparent power rating of 100.0 kVA. The inverter can supply up to 152.0 A of motor current, while the input side draws 157 A from the supply under rated conditions. It accepts a mains input range of 3 AC 380…480 V (-15 % / +10 %) and operates on industrial networks at 50/60 Hz. The converter supports V/f open-loop control, sensorless vector control, and field-oriented control, allowing it to adapt motor operation to different speed and torque requirements.

Speed reference adjustment is available in steps of 0.01 Hz through the front-mounted LCD panel, and settings can also be changed with the integral potentiometer or through the ModBus connection. Pulse-width modulation is fixed at 2.0 kHz, which helps balance switching losses with motor noise. The enclosure is rated IP 20, and the G-frame housing measures 700 mm high, 450 mm wide, and 302.5 mm deep. The unit has a mass of 56.7 kg, which should be considered during cabinet installation. An internal brake chopper is included, but braking energy requires an external resistor for dissipation. A relay contact rated at 230 VAC / 30 VDC / 3 A is provided for fault signaling, and the standard control package includes a PID controller for precise speed regulation.
