Product Description:

The FECP01.2-90K0-3P400-A-BN-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. It is intended for variable-speed control of three-phase induction motors that drive pumps and fans in automated HVAC or process circuits. By altering the output frequency, it helps match flow or pressure to demand, reduce startup current, and extend equipment life. This model belongs to Design 2 of the first generation and comes without a potentiometer, so parameter entry is handled digitally through fieldbus or keypad commands.

Its input configuration is 3-phase and it is rated for the 400 VAC class, while the power stage accepts line voltages from 3 AC 380 to 480 V, permitting installation on common industrial feeders. The drive supplies 90 kW of continuous mechanical power to the motor shaft. For short process surges, it tolerates 120% for 60 seconds, and for extended heavy duty it remains stable at 105% for 60 minutes before thermal limits are reached. These margins help centrifugal pumps ramp to the required head pressure without nuisance trips. An external brake chopper handles excess DC-bus energy produced during deceleration so internal components remain within their temperature range.

Communication with the plant controller is available through the ModBus interface, eliminating analog wiring when adjusting setpoints in the supervisory PLC. The converter occupies Mechanical Size 6 and carries the Big size panel designation, yet its width is just 455 mm, allowing side-by-side mounting in standard cabinets. Its housing meets the IP20 protection class, so cabinet airflow must be maintained during operation. For long service intervals in continuous pump or fan duty, the power stage is rated for high durability. Digital communication also supports straightforward status monitoring and remote speed reference updates from the control system.
