Product Description:

Bosch Rexroth Indramat manufactures the FECG02.1-7K50-3P400-A-SP-MODB-01V01 in its FEC Frequency Converters series. This frequency converter changes fixed-frequency three-phase power into a variable output for induction motors used in general automation cells. It is intended for variable-speed operation on conveyors, pumps, fans, and similar machinery. The unit is part of the second generation of the platform, uses design version 1, and has mechanical size 2 with a small front panel. Its control and power sections are housed in one cabinet-mounted unit, which keeps panel installation straightforward. An internal brake chopper is integrated, and an external braking resistor can be connected to absorb regenerated energy during rapid deceleration.

The converter runs in V/F control mode with a digital frequency resolution of 0.01 Hz, allowing fine speed increments across its 1:100 regulation span. This helps align conveyor flow rates and pump curves with process demands while maintaining simple speed control. Supplied from 3 AC 380 to 480 V, it provides 7.5 kW of rated power and sustains 17 A continuously. The converter can handle overloads of 200% for 1 second and 150% for 60 seconds, which supports 150% start-up torque at 5 Hz. Magnetic-flux PWM modulation with a carrier frequency up to 15 kHz shapes the output waveform, and a built-in potentiometer allows local speed adjustment without external regulators.

Site constraints are addressed through the IP20 enclosure, a width of 220 mm, and reliable operation up to 1000 m of installation altitude. The ambient limit of 40 °C matches most control cabinets, and thermal derating is not required within this range. Communication with supervisory controllers is handled through Modbus, supporting parameter changes and status polling over the plant network. This allows the drive to exchange operating data with higher-level equipment without separate analog reference wiring. The compact housing helps the converter fit densely packed enclosures when normal clearance and cooling guidelines are maintained.
