Product Description:

The FECG01.2-22K0-3P400-A-BN-MODB-01V01 is a Bosch Rexroth Indramat frequency converter in the FEC Frequency Converters series. It is used in general-purpose automation to modulate motor speed by converting fixed three-phase mains power into controlled voltage and frequency for production machines, material-handling lines, and energy-saving pump drives. By varying output frequency and voltage, it helps connected motors start more smoothly and operate at speeds that better match process demand. This approach can improve flexibility in conveyors, fans, and similar machinery that does not need to run at one constant speed.

This model delivers a rated output of 22 kW, giving it enough capacity to run medium-sized drives or multiple smaller motors through a single inverter. A continuous output current of 44 A sets the basic requirement for upstream protection and cabling. The inverter can raise carrier frequency up to 650 Hz, so high-speed spindles or servo pumps can operate above base motor frequency with stable control. Its input window of 3 AC 380 to 480 V allows operation on common industrial power networks used in 400 VAC installations. Short bursts of 200% for 1 second overload let the converter handle demanding acceleration or brief impact loading without tripping. Communication with plant controllers is handled through Modbus, which simplifies parameter access and remote diagnostics.

Additional overload capacity of 150% for 60 seconds keeps torque available during heavy but temporary duty cycles. The enclosure carries an IP20 rating, so it is intended for installation inside a cabinet where the surrounding panel provides added protection. With a cabinet width of 275 mm, the unit fits the big-size panel format while remaining compatible with Mechanical Size 3 mounting rails. An external brake chopper handles regenerative energy during deceleration, which is useful when the driven load returns energy to the DC bus. The design 2, first-generation electronics support 50/60 Hz supplies, 400 VAC class components, and operation up to 1000 m altitude without derating.
