Product Description:

The FECG01.2-90K0-3P400-A-BN-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat in the FEC Frequency Converters series. It modulates three-phase mains power to control induction motor speed and torque in general automation equipment. This allows production lines to match motor output to changing process demand instead of running at a fixed speed. The unit also works with an external brake chopper and braking resistor to dissipate regenerated energy during deceleration rather than sending it back to the DC bus, which helps protect upstream components during rapid stops.

The converter delivers a continuous output current of 183 A and supports loads up to its rated power of 90 kW. A digital frequency resolution of 0.01 Hz allows fine speed adjustment in V/f operation. It provides overload capacity of 200% for 1 second during abrupt acceleration and 150% for 60 seconds during longer surges. These overload levels help the drive handle temporary load increases without immediately reducing performance. Sinusoidal PWM, or SVPWM, is used for modulation to reduce harmonic distortion at the motor terminals. The input accepts three-phase power from 380 to 480 V, which fits common industrial power systems.

Mechanical size 6 hardware measures 455 mm wide, 682 mm high, and 290 mm deep, with a mass of 52.5 kg. Start-up torque reaches 150% at 5 Hz, which helps heavily loaded conveyors begin moving without extra gearing. Across the operating range, the converter maintains a control ratio of 1:100 for stable low-speed operation without encoder feedback. The required supply is 400 VAC, and the enclosure is rated IP20, so the unit should be installed in a cabinet for dusty or wet areas. Setpoint entry is handled by external commands because no potentiometer is built into the unit, and external brake components help keep internal heat lower during repeated stops.
