Product Description:

The Bosch Rexroth Indramat FVCA01.2-1K50-3P4-MDA-LP-NNNN-02VRS is a frequency converter in the FVCA Frequency Converters series. The product is part of series line 01 and uses design revision 2. It is intended for three-phase induction or synchronous motors, and it uses frame size A. Sensorless vector control allows the unit to regulate motor speed and torque for automated production lines without requiring a separate feedback device.

The converter delivers 1.5 kW of output power from an apparent power rating of 2.6 kVA. It operates on a nominal bus voltage of 400 V, draws 5.1 A, and provides 4.0 A during rated operation. Short-term overload capability reaches 150 % for 60 s, and an integrated brake chopper works with an external resistor during deceleration. Sinusoidal SVPWM is generated at a default carrier frequency of 8.0 kHz, and speed commands can be set with resolution down to 0.01 Hz through the LCD panel, the onboard potentiometer, or a Modbus connection. The unit also includes a Class C3 filter and digital vector control with a 1:1000 FOC speed range, a 1:100 service range, and 150% start-up torque at 0.5 Hz. Installation uses M5 screws.

The housing measures 275 mm high, 125 mm wide, and 122 mm deep, and the assembly weighs 2.7 kg. Its enclosure is rated IP 20, so the drive is intended for installation inside a guarded cabinet while still allowing front access to the local interface. The input range of 3 AC 380...480 V (-15 % / +10 %) supports common industrial supply systems, and the converter uses natural convection cooling. Field-oriented control can provide 200 % at 0 Hz start-up torque, which helps free stalled loads at low speed. Excess kinetic energy is dissipated safely during braking, and the switching frequency can be adjusted to suit process noise requirements.
