Product Description:

The FECG02.1-11K0-3P400-A-BN-MODB-01V01-S001 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. Designed for general automation, this second-generation unit follows Design 1 and uses mechanical size 2 with a large front panel for parameter access. It employs V/f control together with SVPWM modulation to provide adjustable motor speed while maintaining torque linearity. An internal brake chopper is fitted, and terminals for an external braking resistor are available for energy dissipation during rapid deceleration. Field devices communicate through the ModBus interface, and because the unit is delivered without a potentiometer, all setpoint changes are handled digitally. The housing is 392 mm high, 220 mm wide, and 218 mm deep, has a mass of 3 kg, and can be mounted at elevations up to 1000 m.

For power connection, the converter accepts a three-phase input in the 380 to 480 V AC range, which places it in the 400 VAC voltage class. Its rated output is 11 kW, delivered continuously at 24 A to support the connected motor within its thermal limits. The unit can vary motor speed across a 1:100 range, and frequency commands can be incremented in steps as fine as 0.01 Hz, enabling precise process tuning. These operating points are synthesized by the inverter so that output voltage maintains a smooth sinusoidal profile and motor noise stays low.

High overload capacity characterizes the drive. It tolerates 200 % for 1 second and 150 % for 60 seconds above its continuous current, and it can generate 150 % at 5 Hz startup torque to accelerate loaded shafts without stalling. The enclosure carries an IP20 protection rating, so it must be installed in a panel that prevents direct contact with live parts while allowing adequate airflow. Panel installation also helps protect the electronics during normal operation.
