Product Description:

The FECP01.2-55K0-3P400-A-BN-NNNN-01V01 is a frequency converter built by Bosch Rexroth Indramat for the FEC Frequency Converters series. It belongs to the first generation, carries the Design 2 revision, and uses mechanical size 5. By modulating incoming AC power, it provides variable-speed control for pump and fan duties in automated processing lines, allowing stable flow or airflow without mechanical throttling. The unit is built for high durability, making it suitable for continuous plant operation where long service intervals and steady performance are important.

The electrical section centers on a rated output of 55 kW and operates from a three-phase supply. Under continuous conditions, the inverter can supply 110 A to the motor, and it uses magnetic flux PWM switching to support smooth output control. The control electronics resolve frequency commands down to 0.01 Hz, which allows precise speed trimming across the operating range and helps maintain stable process response at low command values. During acceleration, the drive produces 150 % at 5 Hz start-up torque so centrifugal loads can begin turning without excessive hesitation. Short-term overload capability reaches 120 % for 60 seconds, and excess regenerative energy during rapid deceleration is handled through an external brake chopper with a matching external resistor.

Mechanical installation uses a cabinet-oriented housing with a width of 364 mm, a depth of 260 mm, and a height of 602 mm, while the big-size panel format uses 11 mm mounting holes. The enclosure carries an IP20 protection class, which is suited to installation inside an electrical cabinet where contact protection is required but exposure to water must be limited. The assembly weighs 33.8 kg, so the mounting surface must support a substantial drive body during operation. Long-term thermal loading can reach 105 % for 60 minutes, and the speed regulation range of 1:100 supports controlled low-speed operation in variable-torque applications. The converter accepts line voltages between 3 AC 380 to 480 V, and because it is supplied without a potentiometer, setpoints are entered digitally through the host control system.
