Product Description:

The FECP02.1-7K50-3P400-A-SP-MODB-01V01 is an adjustable-speed unit produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. It modulates voltage and frequency so centrifugal pumps and axial fans can follow changing flow or pressure demands in automated plants. The converter uses simple V/F control so the connected motor can start smoothly, run quietly, and reduce energy use compared with fixed-speed operation. This makes it suitable for pumping and ventilation duties where demand changes throughout the operating cycle.

With a rated output of 7.5 kW, the device can deliver a continuous motor current of 17 A from a three-phase supply of 3 AC 380 to 480 V. The integrated thermal model permits an overload of 120 % for 60 seconds or 105% for 60 minutes without tripping. Fine low-speed adjustment is possible because the reference increment is only 0.01 Hz. That small increment supports gradual speed changes when flow or pressure must be adjusted in small steps. The open-collector terminal can source 50 mA for status lamps or small relays, and the unit generates the required output frequency instead of passing line voltage directly to the motor.

At startup, the drive can supply 150 % at 5 Hz, which helps produce breakaway torque for heavy impellers. An internal brake chopper sends regenerated energy to an external resistor, allowing controlled deceleration. Design 1 in Mechanical Size 2 gives the unit a compact panel footprint that is 220 mm wide, and the enclosure is rated IP20 for cabinet installation. Communication with supervisory controls is handled through a Modbus interface, and a built-in potentiometer allows local speed adjustment. Both the digital output and encoder input channels operate up to 50 kHz, and speed regulation is maintained across a 1:100 range.
