Product Description:

The FVCA01.1-18K5-3P4-MNA-LP-P001-01V01 frequency converter is manufactured by Bosch Rexroth Indramat for the FVCA Frequency Converters series. It belongs to series line 01, carries release number 01, and is supplied in design revision 1. Through Modbus communication, the unit exchanges commands with a PLC and conditions power from the three-phase mains so that induction or synchronous motors can run at commanded speeds. By varying output voltage and frequency, it allows conveyors, pumps, and similar machines to match load demand without mechanical adjustments.

Electrically, the drive handles an apparent load of 24.0 kVA and can deliver 18.5 kW of shaft power through its inverter section. It accepts a nominal supply of 400 V, and the three-phase input range of 380 to 480 V with -15%/+10% tolerance covers common regional power variations. Under rated conditions, the input side draws 48.0 A and the output side provides 39.0 A. All circuitry is housed in a D frame that measures 225 mm wide, 227 mm deep, and 440 mm high, with cabinet protection rated IP 20. The assembly includes a front-panel potentiometer for manual speed trim, 24 VDC 8 mA digital inputs, an LCD display, and relay contacts rated 30 VDC 3 A. No line filter is fitted, and the internal brake chopper requires an external resistor.

Speed regulation is refined by space-vector PWM that runs at a default carrier of 6.0 kHz and provides frequency steps as small as 0.01 Hz. For analog reference channels, the converter presents a Vr1 input resistance of 100 kOhm, while current-mode inputs have 165 ohms of resistance. A transistor output can sink up to 50 mA for status signaling, and the unit can reach fundamental motor frequencies up to 400 Hz. Despite this capability, the package weighs only 16.5 kg, which helps simplify panel installation.
