Product Description:

The FECG01.1-185K-3P400-A-BN-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. As a first-generation, design 1 unit, it is intended for general automation duties where variable-speed control of induction motors is required. By modulating the output frequency in response to machine commands, the converter coordinates motion profiles and improves energy usage on conveyors, pumps, and other plant equipment. This operating method also helps the connected motor match changing process demand more closely than fixed-speed operation and can reduce mechanical shock during starts.

Electrical integration uses a 3-phase supply within the converter’s 400 VAC voltage class. The accepted mains range of 3 AC 380 to 480 V allows the device to operate on standard industrial power systems. Incoming power is routed through an IP20 housing, which limits finger access while keeping cabinet layouts compact. During abrupt acceleration or indexing, the control stage can deliver up to 200 % for 1 second of rated current, allowing the motor to overcome static friction or brief torque spikes without tripping. These features support standard cabinet integration and stable operation on common industrial power systems.

For sustained demands, the electronics permit 150 % for 60 seconds, so moderate process stalls can clear without external bypass contactors. Power components are mounted on a large-size panel, providing wider spacing for heat dissipation and easier access inside the enclosure. Overall operation is supported by high overload capacity, which suits conveyor starts, press cycles, and heavy mixed loads. Parameter changes are issued exclusively through digital interfaces because the unit is supplied without a potentiometer. This setup avoids reliance on a local analog adjustment and keeps command changes within the control system.
