Product Description:

The FECP02.1-22K0-3P400-A-BN-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. As a second-generation, three-phase unit in the 400 VAC class, it provides variable speed control for centrifugal pumps and axial-flow fans used in process and HVAC installations. By converting fixed mains frequency into a regulated output, the drive adjusts motor speed to match system demand, which helps reduce energy use and mechanical stress on connected equipment.

Its electrical capacity reaches 22 kW and it delivers a continuous motor current of 44 A, while the supply line may draw 51 A under rated load. The input range of 3 AC 380 to 480 V supports use on common industrial power systems, and short-term overload capability of 120% for 60 seconds or 105% for 60 minutes helps the unit handle startup surges. Output frequency can be adjusted in 0.01 Hz steps for fine speed control. The converter uses V/f scalar control with an SVPWM algorithm, and the built-in PID regulator supports closed-loop pressure or flow control. An external brake chopper handles regenerative energy, and the enclosure has an IP20 protection rating. Status is shown on a 4-digit LED display, parameter changes are made from the keypad, and the unit comes without a potentiometer. The Design 1 mechanical size 3 housing provides clear access for wiring.

The enclosure measures 574 mm in height, 275 mm in width, and 236 mm in depth, and the unit weighs 16.9 kg. Cooling slots are arranged for forced-air passages inside the cabinet. The drive offers a speed control range of 1:100, so the same inverter can support both slow-speed flushing and higher-speed purge cycles. Network communication is available through ModBus, and terminal access is placed beside the field I/O strip to keep cabinet wiring short and direct.
