Product Description:

The FECP01.1-75K0-3P400-A-BN-NNNN-01V01 frequency converter is manufactured by Bosch Rexroth Indramat within the FEC Frequency Converters series. This first-generation, design 1 model processes three-phase power to drive asynchronous motors in pump and fan stations used in industrial automation systems where airflow or liquid movement must track changing demand. By varying voltage and frequency, it replaces mechanical throttling and enables proportional flow control while reducing wear. The unit is supplied without an integrated potentiometer, so reference commands are issued by the supervisory controller.

Electrically, the converter is rated for a 380 to 480 V AC, three-phase network in the 400 VAC class and accepts 50 to 60 Hz mains through three input phases. It draws up to 157 A and delivers 152 A to the motor, supporting a continuous shaft output of 75 kW. Output frequency is adjustable from zero up to 650 Hz, with 0.01 Hz digital steps and 0.1% analog resolution, while V/F control maintains the voltage-to-frequency ratio for induction motor flux. This keeps magnetization behavior consistent across the usable speed range. For short overloads, the drive can sustain 120% for 60 seconds, and its external brake chopper dissipates regenerated energy. This level of adjustment supports closed-loop temperature or pressure control where small setpoint changes are required and stable motor response is important.

The converter provides speed regulation of 1:100 and delivers 150% at 5 Hz start-up torque so pumps can reach prime quickly. Apparent power capacity reaches 116 kVA, and the chassis has an IP20 enclosure rating in a size 6 big-panel format that measures 455 mm wide. A secondary overload window of 105% for 60 minutes allows the drive to remain in operation during long drawdown cycles. The wide format leaves space for large power terminals and busbars, which supports higher-current connections and keeps conductor routing straightforward inside the panel.
