Product Description:

The FECP02.1-75K0-3P400-A-BN-MODB-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. As a second-generation design, it provides variable-speed control for industrial pumps and fans in automated plants. The unit adjusts motor frequency and voltage to match process demand, allowing energy savings and precise flow regulation while integrating with supervisory systems through its built-in Modbus interface. It is intended for process equipment that benefits from adjustable motor speed instead of constant full-output operation. This operating method is useful where airflow or liquid flow must respond smoothly to changing process conditions.

With a rated output of 75 kW, the converter draws a continuous three-phase current of 152 A when operated from a supply of 3 AC 380 to 480 V. A V/f control algorithm works with an internal PID controller, and sinusoidal SVPWM modulation helps keep motor operation stable. Start-up torque reaches 150 % at 5 Hz, while an overload capacity of 120 % for 60 seconds supports short acceleration peaks. External brake chopper and braking resistors can be connected for controlled stops. The cabinet-mounted Design 1 unit uses mechanical size 6, spans 455 mm in width, includes a big operator panel for local monitoring, and comes without a potentiometer. Operation is permitted at elevations up to 1000 m above sea level.

During prolonged load conditions, the converter can carry 105% of nominal current for 60 minutes. It maintains a 1:100 speed control range and issues commands in 0.01 Hz steps for fine adjustment. Small command increments help the drive follow gradual setpoint changes in ventilation and pumping duties. The enclosure has an IP20 rating for clean cabinet interiors, and the design belongs to the 400 VAC voltage class used on many factory mains. Protected indoor cabinet installation is appropriate because the enclosure is intended for clean electrical panels rather than open exposure.
