Product Description:

The FECP01.1-315K-3P660-A-BN-NNNN-01V01 is a frequency converter from Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. Built in Design 1, it modulates the AC supply to control motor speed in pump and fan circuits commonly used in industrial automation. By adjusting output frequency instead of relying on mechanical throttling, the unit helps improve energy efficiency and process control in fluid-handling systems. In variable-torque applications, this operating method also supports smoother ramp-up and more stable flow or pressure regulation than fixed-speed motor operation.

This model accepts a 3-phase mains connection that balances current across all lines and minimizes neutral loading. Two overload margins are available: the converter can deliver 120% for 60 seconds to cover rapid acceleration demands, and it can sustain 105% for 60 minutes for extended heavy-duty cycles without a thermal trip. That overload capability helps the drive continue operating through short periods of increased demand instead of reducing output immediately. The enclosure has an IP20 protection class, so the unit must be installed inside a cabinet or other guarded enclosure where dust and accidental finger contact are limited. The control electronics use a large size panel format, which provides added heat-spreading area and clear terminal spacing for large-gauge conductors.

The drive is optimized for pump and fan duty profiles, and its parameter tables match the torque curve of centrifugal loads while supporting soft-start sequencing. Its power stage is built for high durability, allowing continuous service in HVAC or process water circuits where steady operation is important. The control section ships without a potentiometer, so speed references must come from remote analog signals or fieldbus commands. This arrangement simplifies panel cutouts, keeps the front face sealed, and supports integration with centralized control systems.
