Product Description:

The FVCA01.1-18K5-3P4-MNA-LP-NNNN-01V01 is a frequency converter in the FVCA Frequency Converters series from Bosch Rexroth Indramat. As an AC drive controller, it converts three-phase 380–480 V mains power into a regulated motor supply for variable-speed operation in automated machinery. By adjusting motor voltage and frequency, it supports equipment that requires controlled acceleration and stable running speed. The unit is part of Line 01 and design revision 1. It is supplied without a special design variant and is intended for panel-mounted installations.

At a nominal bus of 400 V, the converter can deliver 18.5 kW and provides a rated output current of 39.0 A. Output frequency is adjustable from 0–400 Hz, and the drive supports V/f, SVC, and FOC control modes for use with induction or synchronous motors. The default PWM carrier frequency is 6 kHz. The three-phase supply operates at 50 to 60 Hz with a tolerance of ±5 percent. Short-term overload capability is rated at 200% In for 1 s and 150% In for 60 s. During deceleration, excess energy can be handled through an external brake resistor connected to the chopper. Local and remote adjustment are available through ModBus communication, an onboard potentiometer, and an LCD panel, while forced-air cooling maintains operating temperature.

The converter is built in frame size D and measures 225 mm wide, 227 mm deep, and 440 mm high. It has an apparent power rating of 24.0 kVA and a mass of 16.5 kg. Installation is permitted up to 1000 m above sea level, and the enclosure has an IP20 rating for protection against accidental contact with live parts. The enclosure is intended for installation inside a control cabinet rather than for open mounting. The unit is supplied without an internal EMC filter, so external filtering is required where radio-interference suppression is needed.
