Product Description:

The FECP01.1-110K-3P400-A-BN-NNNN-01V01 belongs to the FEC Frequency Converters series produced by Bosch Rexroth Indramat. This frequency converter interfaces with three-phase 380 to 480 VAC networks and supplies variable voltage and frequency to induction motors used in pump and fan installations. By modulating the mains waveform, it enables process-dependent speed regulation, lowering energy use while maintaining the mechanical demands typical of fluid-handling equipment.

The drive is specified for a continuous output of 110 kW and can deliver 223 A without derating when mounted within its 570 mm wide Size 7 housing. Pulse generation uses SVPWM, improving motor current quality compared with sinusoidal PWM. Digital commands are adjustable in steps of 0.01 Hz, and analog references hold a precision of 0.05%, supporting accurate closed-loop flow or pressure control. External brake chopper and resistor assemblies dissipate regenerated energy, while the internal V/f algorithm maintains constant flux across the 400 VAC voltage class. A four-digit LED panel on the large front door presents setpoints and fault codes, and the design 1 control platform is intended for long service intervals.

An operating range of 1:100 allows the converter to reduce shaft speed to 1% of nominal without stalling the load. For breakaway conditions, it produces a start-up torque of 150% at 5 Hz, giving centrifugal pumps sufficient margin against static head. Short-term overload is accommodated at 120% for 60 seconds, and a one-hour rating of 105% provides additional thermal headroom during process upsets. The open-frame IP20 protection class requires installation in a clean electrical enclosure at altitudes up to 1000 m. The absence of a potentiometer shifts all speed setting to the digital interface, which helps prevent drift over time.
