Product Description:

The FECG02.1-4K00-3P400-A-SP-MODB-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat for the FEC Frequency Converters series. It is a second-generation unit with design version 1 and is intended for general automation systems that require variable-speed control of induction motors. The unit belongs to the 400 VAC class and uses U/f control with a freely adjustable V/f curve to match motor voltage and frequency to the application. This supports energy-efficient operation in conveyors, fans, and pumps across a wide range of plant equipment.

The converter delivers a rated output of 4.0 kW at a continuous current of 10 A and accepts a three-phase 380 to 480 V mains input in a chassis that is 125 mm wide. Space-vector PWM creates the output waveform, enabling a speed control range of 1:100 with start frequencies adjustable in 0.01 Hz steps and shown on the 4-digit LED display. Commands can be entered through ModBus or by using the built-in potentiometer, and linear or S-curve ramps manage acceleration. An internal brake chopper works with an external resistor to dissipate regenerated energy. For short overload events, the drive tolerates 200 % for 1 second, which supports high-overload operation.

During startup, the inverter supplies 150 % at 5 Hz torque so loads such as conveyors or presses can overcome static friction before reaching nominal speed. A second duty rating permits 150 % for 60 seconds, covering longer temporary load peaks without tripping. The housing has an IP20 protection class, weighs 3.2 kg, and corresponds to mechanical size 1 with a small operator panel for straightforward cabinet integration. Analog speed inputs are processed with 0.05 % setting accuracy, and the programmable curve capability lets the drive match torque behavior to different loads while maintaining efficient motor control.
