Product Description:

The FECG01.2-1K50-3P400-A-SP-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat and supplied within the FEC Frequency Converters series. It is intended for general automation where variable-speed control of three-phase induction motors is required. By converting the incoming 400 VAC mains to a modulated output, it permits precise motor speed adjustment while maintaining torque, making it suitable for conveyor sections, compact pumps, and small process machines.

This converter is housed in an IP20 enclosure that measures 125 mm in width and weighs 3.0 kg, allowing installation inside a ventilated panel. The unit delivers up to 1.5 kW of rated motor power and a continuous apparent power of 3 kVA. Its input side accepts three-phase 380 to 480 VAC at a rated current of 6 A, while the output side supplies 4 A through magnetic-flux PWM modulation. A digital frequency resolution of 0.01 Hz supports fine speed trimming under V/F control. Forced, temperature-controlled air moves through the chassis to remove heat, and an internal brake chopper dissipates regenerated energy during rapid deceleration. Eight digital inputs, three analog inputs, two analog outputs, and a single RS-485 Modbus port allow interaction with PLCs and local potentiometer settings.

The drive can develop 150% at 5 Hz start-up torque, enabling heavy loads to break inertia at low speed. During transient events it tolerates 200% for 1 second, and for longer duty it sustains 150% for 60 seconds. Speed stability is supported by a regulation ratio of 1:100, so low-speed operation remains steady without an encoder. The converter uses a first-generation control board, design version 2, and a size 1 mechanical frame, which helps keep panel depth minimal. The small front panel includes a built-in potentiometer, and the voltage class matches 400 VAC installations without requiring isolation transformers.
