Product Description:

The FECG02.1-1K50-3P400-A-SP-MODB-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. This second-generation, design 1 model is intended for general automation duties that require adjustable motor speed from a three-phase mains supply. It uses mechanical size 1 hardware and includes a small control panel with an integral potentiometer. Its compact width of 125 mm helps it fit in tight electrical compartments where panel space is limited. The front controls allow quick local interaction when a simple speed reference or status check is needed at the machine.

Control resolution of 0.01 Hz allows fine speed adjustments during setup and normal operation. The converter accepts an input line frequency of 50 – 60 Hz (±5%) and uses an internal brake chopper with a space-vector inverter that applies SVPWM switching from 1 to 15 kHz. Output frequency is continuously variable from 0 to 599 Hz, allowing four-pole motors to run well above base speed when the application requires it. Rated power is 1.5 kW, and the drive can withstand a short-term overload of 200 % for 1 second. It also provides 150% start-up torque at 5 Hz, which helps when a load must begin moving under higher resistance. This control behavior is useful for applications that need smooth ramping rather than abrupt changes in motor speed.

A second overload curve allows 150 % for 60 seconds, after which current returns to the nominal rating of 4 A to help control thermal rise. The unit is built for the 400 VAC voltage class and has an IP20 enclosure, so it is intended for installation inside a protected cabinet. Reliable operation is maintained from −10 °C to +40 °C in ambient humidity below 90% without condensation. The Modbus interface supports diagnostics and drive access, while vector modulation helps keep motor current smooth across a wide speed range. Those operating limits suit enclosed industrial panels where airborne moisture must be controlled to protect energized components.
