Product Description:

The FECP01.2-22K0-3P400-A-BN-NNNN-01V01 is a frequency converter built by Bosch Rexroth Indramat for the FEC Frequency Converters series. It is part of the first generation and uses Design 2 within that product line. By supplying variable output to induction motors, the unit provides speed control for pump and fan duties and helps reduce throttling losses in systems that do not need constant full-speed operation. This operating method lets the motor speed follow process demand more closely than fixed-speed operation. The converter uses Mechanical Size 3 and has a front panel width of 275 mm. An external brake chopper can be connected when dynamic stopping is required.

This model draws power from a three-phase AC supply in the 380 to 480 V range, and the nominal voltage class is 400 VAC. At line frequencies of 50 to 60 Hz with a tolerance of ±5%, it absorbs 34 A from the mains and delivers 44 A to the load. The drive has an active output of 22 kW, making it suitable for larger pump and fan motors that require stable speed adjustment. V/F control is supported with a digital resolution of 0.01 Hz, so precise speed steps can be set across the programmable range of 0-650 Hz. The unit can also produce 150% torque at 5 Hz during startup, and it can be installed at elevations up to 1000 m above sea level without derating.

During overload, the drive can sustain 120% for 60 seconds and remain at 105% for 60 minutes, which covers both brief surges and longer periods of elevated demand. That combination is useful where pumps must start under load or where fans may see temporary demand increases. Speed regulation is supported by a ratio of 1:100, allowing stable low-speed operation as well as normal full-flow service. The enclosure has an IP20 protection class, so the converter should be mounted inside a cabinet while still providing touch-safe shielding in indoor machinery areas. The unit does not include a built-in potentiometer on the front panel, and the design is intended for continuous operation within the stated voltage, temperature, and altitude limits.
