Product Description:

The FECP02.1-90K0-3P400-A-BN-MODB-01V01 is manufactured by Bosch Rexroth Indramat for the FEC Frequency Converters series. As a second-generation unit, it controls three-phase pump or fan drives by adjusting supply frequency to match process demand. The converter fits mechanical size 6 enclosures and measures 455 mm in width, 682 mm in height, and 290 mm in depth, with a weight of 52.5 kg. It uses a large front panel that leaves room for field wiring, and it operates from a 3 AC 380–480 V supply in the 400 VAC class. Regenerated energy is handled through an external brake chopper.

Control is based on V/f technology supervised by a PID controller, allowing steady speed regulation in variable-torque applications. Fine frequency setting is possible because the analog input has a tolerance of 0.05%, while the digital reference is resolved to 0.01 Hz. During steady operation, the inverter delivers a continuous current of 183 A to the motor and supports mechanical output up to 90 kW. For short-term demand, it can withstand 120% for 60 seconds above the rated load, and the input stage can draw 187 A from the mains. Space-vector pulse-width modulation is used to reduce harmonic content across the modulation range, and the unit is supplied without a potentiometer so settings are entered digitally.

For extended overloads, the drive can carry 105% for 60 minutes, and at startup it develops 150% at 5 Hz to help overcome static friction in heavy impellers. The closed-loop range reaches 1:100, allowing stable low-speed ventilation without feedback devices. The enclosure rating is IP20, so the converter is intended for installation inside a protected cabinet, and configuration and diagnostics are handled through the ModBus interface. It is built for durable operation and uses the Design 1 layout.
