Product Description:

The FVCA01.1-45K0-3P4-MDA-LP-P002-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FVCA Frequency Converters series. It regulates three-phase induction or synchronous motors by converting a fixed mains supply into variable frequency and voltage for speed and torque control. As a factory-installed drive component, it supports plant-wide coordination through the Modbus interface, while a built-in potentiometer provides local adjustment.

The converter has an apparent power of 62.0 kVA and an output rating of 45.0 kW. It operates from a nominal 400 V network across a three-phase 380 to 480 V range (-15%/+10%) and accepts 50/60 Hz input. A rated input current of 104.0 A is converted to a motor current of 95.0 A through SVPWM modulation under V/f, SVC, or FOC control modes. Under FOC control, closed-loop accuracy is 0.05% of maximum frequency, and startup torque reaches 200% at 0 Hz. An external braking resistor can be connected to the built-in chopper to dissipate regenerative energy. The converter also includes PID regulation, relay contacts rated at 230 VAC or 30 VDC at 3 A for status signaling, and a Class C3 EMC filter for industrial environments.

The unit uses frame size F and has an enclosure rating of IP 20. Its dimensions are 650 mm high, 325 mm wide, and 265 mm deep, and its mass is 37.0 kg. A front LCD panel displays parameters, and the default carrier frequency is 2.0 kHz for balanced acoustic and thermal performance. Set-point adjustment is available in minimum steps of 0.01 Hz, and operation is permitted up to 1000 m altitude without derating. The unit is design revision 1, full version 01, release number 01, and series line 01. External brake connections, Class C3 filter wiring, and Modbus connections use top-mounted terminals.
