Product Description:

The EFC5610-30K0-3P4-MDA-7P-FCPNN-L1NN frequency converter is manufactured by Bosch Rexroth Indramat within the EFC Frequency Converters series. Designed for variable-speed control of three-phase induction motors, the unit converts fixed mains input to an adjustable output, allowing precise speed regulation in pumps, fans, and general machinery. It integrates into control cabinets as a compact component and belongs to product line 02 of the manufacturer’s drive portfolio.

The incoming supply is rated at 400 V, with an allowable range of 380–480 V to accommodate regional power variation. At this voltage, the inverter can deliver a continuous output current of 60.8 A, enough to energize heavy-duty induction machines under vector control. The apparent power limit is 40.0 kVA, and energy is transferred over a three-phase bus for balanced loading. A Flex-Control section with standard I/O supports hard-wired run, fault, and speed references, while the internal industrial-grade C3 EMC filter curbs conducted emissions. The standard LCD interface with a potentiometer supplies local setpoint adjustment, and the housing’s IP20 rating limits use to protected electrical rooms where finger-safe access is sufficient.

For applications that demand high overload, the converter’s heavy-duty channel sustains 30.0 kW of mechanical output without thermal derating. The enclosure corresponds to frame size H, so mounting holes and busbar spacing follow the upper end of the EFC 5610 mechanical grid. Functional safety is addressed by the built-in Safe Torque Off circuit that disconnects drive energy without requiring external contactors. Remote supervision is available through the embedded Modbus port, enabling parameter access from PLCs or HMIs. Speed accuracy is maintained by sensorless field-oriented control, identified by the Standard Vector control mode, which modulates flux and torque in real time to keep motor response linear during load swings.
