Product Description:

The FVCA01.2-0K40-3P4-MNA-LP-NNNN-02VRS is a variable-speed frequency converter produced by Bosch Rexroth Indramat within the FVCA Frequency Converters series. It converts fixed mains power into a regulated output for precise motor speed control in automated production cells. This type of drive is well suited to small three-phase motors used in conveyors, fans, and similar equipment that benefits from adjustable acceleration and stable running speed. The unit is delivered in frame size A and comes in release state 02VRS.

Electrically, the converter accepts a three-phase AC mains supply from 380 to 480 V and regulates the motor through a nominal output of 400 V. Within this operating range, it supplies 0.4 kW of power while drawing a rated input current of 1.6 A, for an apparent power of 0.8 kVA. Speed control uses an analog set accuracy of 0.05%, a digital frequency resolution of 0.01 Hz, and an 8.0 kHz carrier that sets the default PWM switching frequency. Vector control supports a 1000:1 FOC range and a 100:1 V/f range, with commanded frequency reaching 400 Hz. Parameter settings are handled from a front-panel potentiometer and LCD, while Modbus communication and an integrated brake chopper support connection to systems that use an external brake resistor. No RFI filter is fitted, so EMC measures must be provided elsewhere in the installation.

The drive delivers a continuous output current of 1.3 A and is housed in an enclosure that measures 275 mm high, 125 mm wide, and 122 mm deep, with a weight of 2.7 kg. Its enclosure carries an IP 20 protection category, so it must be mounted in a covered control panel where contact with live parts and dust exposure are limited. Operating temperature ranges from -10 °C to 40 °C, provided relative humidity remains below 90%. Mechanical data are fixed at design revision 2, and the compact housing helps the unit fit into control cabinets where space is limited.
