Product Description:

The FECP02.1-55K0-3P400-A-BN-MODB-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat for the FEC Frequency Converters series. It is a second-generation, design 1 unit that operates on three-phase power in the 400 VAC class and regulates induction motors with space-vector PWM and V/F control supervised by an internal PID loop. Communication with higher-level controllers is handled through the Modbus interface. The unit is intended for pump and fan drives, fits a mechanical size 5 frame, carries an IP20 protection class, and is 364 mm wide. This layout suits installation inside standard control enclosures, where an external brake chopper and braking resistor can also be mounted.

The drive is rated for 55 kW of continuous mechanical output and supplies a continuous line current of 110 A, allowing full-load operation of industrial motors in this power class. Speed commands entered digitally are resolved down to 0.01 Hz, while analog references are processed with a tolerance of 0.05%. These values help the converter hold a stable process point during variable-speed operation. The permissible input spans 3 AC 380 to 480 V, covering common low-voltage industrial grids. A large operator panel supports local parameter entry, and the unit is supplied without a potentiometer, so speed trimming is expected to occur through the control network.

For transient events, the electronics permit an overload of 120% for 60 seconds, and for extended heavy service they sustain 105% for 60 minutes. These limits protect the power stage while giving connected equipment time to recover from short-term bottlenecks. Acceleration from rest is supported by a start-up torque of 150% at 5 Hz, which helps overcome static friction during startup. Across normal duty, the speed regulation range of 1:100 allows one motor setup to cover both low-flow and full-capacity operation. The external braking components support controlled deceleration in pump and fan applications.
