Product Description:

The Bosch Rexroth Indramat FECG01.2-45K0-3P400-A-BN-NNNN-01V01 belongs to the FEC Frequency Converters series. It works as a variable-speed interface between a three-phase mains supply and induction motors used throughout general automation lines, allowing motor speed to match process demand. The unit is a first-generation device with design version 2 and uses U/f regulation for conveyors, mixers, and other constant-torque loads. It adjusts output voltage and frequency in a predictable way for routine speed control in industrial machinery, and it is suited to applications that need repeatable speed changes rather than positioning functions.

The converter delivers a rated output of 45 kW and accepts a 3 AC 380 to 480 V supply through its three-phase input terminals. Speed can be trimmed in 0.01 Hz increments, which helps with low-speed adjustment and smooth ramp changes. The control section uses space-vector PWM and includes an external brake chopper for dynamic braking energy. With an overload capacity of 200% for 1 second, the drive can handle short acceleration peaks before returning to continuous duty. Its IP20 enclosure is intended for cabinet installation, and commands are entered through the large front panel or a bus interface because the unit does not include a potentiometer.

The frame corresponds to mechanical size 5 and has a width of 364 mm, which allows room for the power modules while fitting standard control cabinets. The converter uses a speed range of 1:100 and provides a start torque of 150% at 5 Hz, helping loaded conveyors begin moving at low speed. Continuous operation is permitted from -10 °C to 40 °C, at up to 90 percent relative humidity, and at installation heights of 1000 m without derating. For heavier duty cycles, it can withstand 150% for 60 seconds before thermal cutback occurs.
