Product Description:

The FECG01.2-4K00-3P400-A-SP-NNNN-01V01 frequency converter is built by Bosch Rexroth Indramat for the FEC Frequency Converters series. Designed for general automation, it turns fixed-frequency plant power into an adjustable output so AC motors can match process demands without relay-based speed control. The unit supports the 400 V industrial distribution class and incorporates motor-side braking energy management, allowing compact installation in machinery that requires repeatable acceleration, soft starting, and accurate speed holding. This operating approach is useful in conveyors, pumps, and similar equipment where smoother speed changes can reduce mechanical stress during normal operation.

Electrically, the converter accepts a 3-phase supply within 3 AC 380 to 480 V and delivers a continuous output of 4.0 kW. Its nominal link voltage corresponds to 400 VAC, aligning it with common industrial switchgear and power distribution practices. An internal brake chopper dissipates regenerated energy, so an external resistor is not required for many standard braking conditions. High overload capability is available because the drive tolerates 200% for 1 second to cover abrupt torque spikes and sustains 150% for 60 seconds during heavier startups or short process surges. These overload reserves help the converter maintain motor control during rapid load changes without forcing routine operation beyond its intended duty.

With a width of 125 mm, the converter fits compact control panels where rail space is limited. Protection to IP20 means live parts are guarded against fingers and similar objects when the unit is installed in a closed enclosure. Operators can trim output frequency directly through the built-in potentiometer, allowing local adjustment without added external control hardware. Its slim form factor helps leave room for wiring ducts, breakers, and neighboring control components in the same enclosure. The device is in Design 2 of the 1st generation family.
