Product Description:

The FECP02.1-37K0-3P400-A-BN-MODB-01V01 is produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. It regulates induction motors that drive pumps and fans in industrial applications by applying scalar U/f control. This second-generation, design 1 unit combines a 4-digit LED display with a large front panel, and remote communication is handled through a dedicated fieldbus port. The local interface supports routine monitoring and direct access to operating values during normal use.

The converter accepts a three-phase supply in the 380 to 480 V range and is rated as 400 VAC. It provides 37 kW of rated output, and carrier-based SVPWM switching gives a digital resolution of 0.01 Hz with an analog frequency accuracy of 0.05%. Continuous current is 75 A, and short-term loading reaches 120 % for 60 seconds with a permissible 105% level for 60 minutes. A 1:100 speed control range is available, and the unit uses an external brake chopper for regenerated energy because it is supplied without a potentiometer. Setpoints therefore arrive through the keypad or over the network, which suits airflow and water-flow control where smooth motor response is important.

The mechanical size 4 housing measures 290 mm wide, 236 mm deep, and 574 mm high, and the assembly weighs 22 kg. The enclosure has an IP20 protection class for installation inside ventilated cabinets. This rating helps protect against accidental finger contact, but cabinet mounting is still required because the housing is not intended to resist dripping water. During acceleration, the drive supplies 150 % at 5 Hz startup torque so loaded impellers can begin turning without hesitation, and the internal thermal model supervises the 105% long-term overload limit. Wiring terminals include the front-mounted Modbus communication connector, which gives the drive a direct serial interface for external control and status exchange.
