Product Description:

The FVCA01.1-90K0-3P4-MDA-LP-P002-01V01 frequency converter is produced by Bosch Rexroth Indramat within the FVCA Frequency Converters series. The device conditions power from three-phase mains and supplies 0 to 400 Hz output for induction or synchronous machines used in automated lines. It communicates through Modbus and can be adjusted directly through a front-mounted potentiometer. V/f, SVC, and FOC control modes are supported, and an integrated PID regulator provides closed-loop speed or pressure control. Switching is handled at a 2.0 kHz carrier with an SVPWM method, and status and parameter values are shown on the LCD display. The unit is design revision 1 and version 01.

Electrically, the converter is rated for a nominal bus of 400 V and can draw 184 A from the supply to deliver a continuous output current of 176.0 A. Within the permitted range of 3 AC 380…480 V (-15%/+10%), the unit supplies up to 90.0 kW of mechanical power, while the apparent power at the feeder reaches 116.0 kVA. The incoming energy is rectified and raised to a DC link equal to the mains voltage multiplied by 1.41 before pulse-width modulation. The converter uses frame size G and is supplied with a factory-installed C3 EMC filter for industrial environments. It also accepts 50 Hz or 60 Hz grids, and the enclosure measures 450 mm in width, 302.5 mm in depth, and 700 mm in height.

Transient demands are handled through an overload margin of 200 % In for 1 s; 150 % In for 60 s, allowing short accelerations without drive shutdown. Thermal limits are set by an operating range of -10 to +40 °C, with permissible humidity below 90% RH, and the enclosure has an ingress rating of IP 20. Braking energy is dissipated through an external resistor because the internal brake chopper is prepared but not populated. The housing weighs 58.0 kg, and the unit is release 01 in Line 01.
