Product Description:

The FECG01.1-1K50-3P400-A-SP-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. Designed for general automation, the device modulates motor speed by altering output frequency while maintaining useful torque across normal operating ranges, allowing fixed-speed motor systems to be replaced with electronic speed control in conveyors, fans, and similar equipment. This first-generation, design 1 model fits mechanical size 1 in a small panel format, so it can be integrated into compact control cabinets where installation space is limited.

Rated at 1.5 kW, the converter can supply the continuous power required by fractional-horsepower pumps, fans, and indexing conveyors. It accepts an input of AC 380 to 480 V, supporting common industrial mains used in production facilities. A 3-phase connection distributes current across three conductors, which helps support efficient motor operation. The housing carries an IP20 protection class, so installation inside a grounded cabinet is necessary to prevent contact with live parts. For rapid torque demands, the electronics tolerate an overload of 200% for 1 second, allowing the motor to accelerate heavier loads without immediate derating.

Longer duty surges are handled at 150% for 60 seconds, which suits applications that alternate between light motion and brief clamping or cutting operations. An internal brake chopper routes regenerative energy to a resistor network inside the unit, protecting the DC link when high-inertia loads decelerate. With a compact frame only 125 mm wide, multiple converters can be mounted side by side on a single plate in multi-axis machines. The front panel comes with a potentiometer, allowing quick manual frequency adjustments during local setup without external programming tools.
