Product Description:

The FECG02.1-110K-3P400-A-BN-MODB-01V01 is an AC frequency converter manufactured by Bosch Rexroth Indramat and assigned to the FEC Frequency Converters series. Designed for general automation tasks, the unit converts constant mains input into a variable output that lets three-phase motors accelerate, run, or decelerate under closed-loop speed control. Integration into plant controls is handled through a built-in Modbus interface, while an external brake chopper can be connected for dynamic energy absorption.

Its rated power of 110 kW pairs with a continuous rated current of 223 A, giving the drive the thermal margin needed for demanding 24-hour duty. The voltage class is 400 VAC, with a permissible line window from 380 to 480 V, so the converter can be connected directly to standard industrial feeders. Digital frequency commands are processed with a resolution of 0.01 Hz, and the space-vector PWM stage operates from 1 to 6 kHz; together these parameters allow fine output adjustments with low harmonic content. For short bursts, the inverter withstands an overload of 200% for 1 second, enabling rapid acceleration or torque boosts. Speed can be regulated over a 1:100 range, and a start-up torque of 150% at 5 Hz maintains breakaway capability even at low shaft speed. Operation without a potentiometer shifts all setpoint entry to the digital control port, simplifying panel wiring.

Mechanical size 7 hardware is supplied on a large panel that measures 570 mm in width and weighs 96.5 kg, so cabinet planning must allow adequate mounting space. Protection is rated at IP20, so the converter should be installed in a closed electrical enclosure where conductive dust or liquids are not present. During longer load surges, it tolerates an overload of 150% for 60 seconds, while continuous service is permitted between −10 °C and +40 °C at relative humidity below 90% and up to 1000 m elevation. Generation-2 design features such as SVPWM modulation and high overload capacity help maintain smooth torque during changing load conditions.
