Product Description:

The FVCA01.1-0K75-3P4-MNA-LP-NNNN-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat within the FVCA Frequency Converters series. The unit modifies three-phase line power into a controllable output for induction or synchronous motors. This allows closed-loop speed and torque regulation in material-handling, pump, and fan applications. It is intended for systems that need adjustable motor speed together with controlled torque output.

The inverter delivers up to 0.75 kW at a nominal line voltage of 400 V, and it runs from three-phase mains. Its input current is 3.7 A, and the output current is limited to 2.5 A. Apparent power is 1.6 kVA, and a 1-second overload capability of 200% In supports short acceleration peaks. Carrier modulation is fixed at 8.0 kHz, allowing the vector algorithm to use a digital frequency step of 0.01 Hz. This resolution is paired with a service-mode accuracy of 0.5% and a field-oriented accuracy of 0.05% of maximum frequency, with a closed-loop vector range of 1:1000 when an encoder is connected. With encoder feedback, the drive can maintain stable low-speed operation during changing load conditions. The LCD panel, integral potentiometer, and Modbus port provide local and network parameter access, and these interfaces allow operating values to be adjusted from the front of the unit or through a connected controller. No RFI filter is fitted, so external filtering may be required.

For panel installation, the drive uses frame size A, measures 125 mm wide, 122 mm deep, and 275 mm high, and weighs 2.7 kg. An integrated brake chopper handles regenerated energy, and braking duty above its threshold is directed to an external resistor. Field-oriented control provides 200% at 0 Hz starting torque, which supports full-load breakaway from standstill. The converter accepts a three-phase supply of 380 to 480 V AC (-15% / +10%) and has an enclosure rating of IP20.
