Product Description:

The FECG02.1-0K75-1P200-A-SP-MODB-01V01 frequency converter is manufactured by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. Designed for general automation, it converts single-phase supply power into a variable three-phase output so that standard induction motors can match process demands without added mechanical devices. Its integrated drive electronics and fieldbus connectivity allow it to fit inside compact control panels while maintaining consistent torque during startup and transient loading.

Speed generation is handled by a V/f control core that works with space-vector PWM, and the switching pattern is updated at up to 15 kHz to provide smooth motor currents. Output frequency can be adjusted in 0.01 Hz steps and rises to 599 Hz, giving a 1:100 speed control range for fine positioning or rapid throughput. A startup torque of 150 % at 5 Hz supports heavy loads, and the internal brake chopper works with an external brake resistor to dissipate regenerated energy. Overload capacity is listed as 200 % for 1 second or 150 % for 60 seconds, which supports short acceleration and deceleration demands. The converter supplies 0.75 kW of rated power from a single-phase input, and a built-in potentiometer, a 4-digit LED panel, a Modbus interface, and a 3 A relay output provide both local and networked control options.

The drive uses mechanical size 1, occupies only a 125 mm width, and includes a small operator panel suited to tight cabinets. The enclosure carries an IP20 protection rating, so the device must be installed inside a cabinet while remaining touch-safe in normal use. Operation remains reliable up to 1000 m elevation and in relative humidity below 90%. The second-generation electronics in Design 1 packaging help conserve panel space.
