Product Description:

The FECP01.2-22K0-3P400-A-BN-MODB-01V01 frequency converter is manufactured by Bosch Rexroth Indramat within the FEC Frequency Converters series. It is designed to regulate motor speed in automated pump and fan systems, allowing flow and air movement to track changing process demand instead of running continuously at full output. By varying output frequency and voltage, the converter supports smoother process response during startup, setpoint changes, and normal load shifts. That makes it suitable for duty cycles in which airflow or pump output must follow process demand over time rather than operate at a fixed speed.

This unit delivers a rated output of 22 kW and accepts a supply range of 3 AC 380 to 480 V. It is intended for a 3-phase mains network, and communication is available through ModBus for parameter access and diagnostic exchange with connected control equipment. Protection against accidental finger contact is provided by an IP20 housing, while an external brake chopper handles regenerated energy during rapid deceleration. The enclosure uses size 3 hardware with a large front panel that is 275 mm wide, which helps the converter fit organized cabinet layouts. The stated input range matches common industrial supply conditions used in 400 VAC installations.

Overload capacity is set at 120% overload for 60 seconds to cover short acceleration peaks or temporary demand spikes. It can also sustain 105% overload for 60 minutes when elevated load remains present for a longer interval in variable-torque service. The converter comes with no potentiometer, so speed references are expected from external signals rather than a front-mounted dial. That arrangement suits installations where commands are issued by a PLC or other remote automation device. The absence of an onboard speed knob also reduces the chance of unintended manual changes during automatic operation.
