Product Description:

The FECG01.2-4K00-3P400-A-SN-NNNN-01V01 frequency converter is manufactured by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. It is intended for general automation applications that require variable-speed control of three-phase motors, converting a fixed 400 VAC supply into adjustable voltage and frequency. This allows connected motors to run at speeds that match process demand in equipment such as conveyors, fans, and pumps. The unit is installed in machine cabinets and connects to induction motors through standard shielded power leads, which help reduce electrical noise between the converter and the motor.

This Design 2, first-generation device operates on a three-phase supply at 50/60 Hz with an input range of 3 AC 380 to 480 V and a permitted line variation of ±10%. It has a high overload capacity, and its IP20 housing, which is 125 mm wide, contains a magnetic flux PWM stage rated at 4.0 kW. The converter produces an output frequency range from 0 to 300 Hz with an incremental resolution of 0.01 Hz, allowing precise speed trimming. During acceleration, the internal brake chopper and heat sink can handle surges of 200 % for 1 s, while loads sustained for one minute may reach 150 % of the rated current without an alarm. The mechanical size 1 frame and compact front panel help save cabinet space, and the output voltage follows the incoming line potential so no external transformer is required. The speed regulation ratio of 1:100 supports slow jog operation as well as rated-speed running under constant torque conditions.

Terminal current is limited to 10.0 A, so protective devices can be sized to match the converter. Frequency deviation remains within ±5 % of the reference value, supporting stable motor control during operation. Installations up to 1000 m above sea level do not require derating. The unit does not include a potentiometer and instead relies on digital setpoints from the machine controller. Its 400 VAC voltage class keeps it compatible with common factory power systems and supports integration into standard industrial power distribution.
