Product Description:

The FECP01.1-220K-3P400-A-BN-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. In pump-driven and fan-driven automation cells, it modulates motor speed so flow or pressure follows process demand instead of line frequency. That operating role suits variable-torque loads where fixed-speed motors would waste energy at partial demand. The unit is Design 1 in the first product generation, so it follows the wiring layout used in early FEC cabinet installations.

This converter is engineered for a 3-phase mains supply and operates over a wide range of 3 AC 380 to 480 V, centered on the 400 VAC class used in many industrial switchboards. This input range allows the drive to run on common three-phase distribution systems used in industrial facilities. Drive electronics are sized so that the output can rise to 120% for 60 seconds during short overloads and maintain 105% for 60 minutes during extended moderate loading. This overload capability supports temporary demand increases in variable-torque applications while protecting the thermal design. High-frequency components are mounted on a large rear-mounted heat sink, and the first-generation control core uses the parameter structure associated with this design.

The enclosure carries IP20 protection, so it must be installed inside a grounded electrical cabinet. A large front panel provides clear terminal labeling and straightforward access to the control area. Control adjustments are handled by the fieldbus or keypad because the drive is supplied without a potentiometer, which avoids analog drift in speed references. Continuous duty at elevated carrier frequencies is supported by the converter’s high durability power stage, which resists vibration and thermal cycling common in plant rooms.
