Product Description:
The FECP02.1-18K5-3P400-A-BN-MODB-01V01 frequency converter is produced by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. Designed for pump and fan duties, it adjusts the supply frequency fed to an induction motor so flow or pressure tracks real-time process demand in automated installations. This second-generation unit is delivered in mechanical size 3 with a large front panel, and it uses an external brake chopper to absorb regenerated energy during fast stops or speed reductions. The lack of a potentiometer means all speed references must be provided through digital control channels, which suits centralized control systems that send commands from a PLC or supervisory controller.
The inverter supplies 18.5 kW of rated output, giving it sufficient capacity for medium-frame centrifugal pumps. It operates from AC 380 to 480 V utility feeders and is wired to a 3-phase mains network, which helps keep current draw balanced across the supply. For short-term torque assist, the power stage sustains 120% for 60 seconds above nominal load before thermal limits intervene. Protection class IP20 means the terminals are finger-safe, but the housing is not sealed against airborne contaminants, so the device should be installed inside a clean electrical enclosure. This arrangement is common in control cabinets where surrounding components provide the protected environment needed for reliable operation.
For extended stress events, the unit tolerates 105% for 60 minutes, allowing continuous operation under slight overload without triggering a fault. All power components are designed for the 400 VAC voltage class, which matches common low-voltage distribution equipment used with industrial drives. Field communication is handled through the native ModBus interface, which provides access to drive registers for speed commands, status data, and diagnostics. Cabinet planning is eased by the housing width of 275 mm, and the large panel leaves room for field wiring. Even without a built-in potentiometer, the Design 1 construction focuses on durable operation in demanding pump and fan applications.
