Product Description:

The EFC5610-1K50-3P4-MDA-7P-C10NN-NNNN is a variable-speed frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. In an automation cell, it sits between the plant supply and an AC motor. It converts fixed-frequency mains into a controllable output so that conveyors, pumps, or process drives can accelerate, decelerate, and hold setpoints demanded by a PLC.

The power stage accepts a nominal 400 V three-phase line at 380 to 480 VAC ±10% and delivers adjustable voltage and frequency to loads up to 1.5 kW in heavy-duty service. Speed accuracy is achieved through standard vector control SVC, which produces torque even at low rotor speeds by regulating current in real time. Network integration uses Modbus, allowing the host controller to read parameters and issue commands over an RS-485 link. An internal EMC filter rated for industrial area, class C3 limits conducted emissions in typical factory environments. The converter is designed for three-phase input only, eliminating single-phase derating calculations. Control logic follows the standard configuration and employs Flex-Control with Standard I/O so discrete sensors or relays can be wired directly to the terminal strip for local start, stop, or fault reset.

User interaction is through a standard LCD display with potentiometer. The screen shows output frequency, current, and fault codes, while the front-panel knob offers quick manual tuning during setup. The mechanics correspond to frame size C, giving enclosure dimensions that match common mounting templates for this power class. A protection rating of IP20 allows installation inside a switchgear cabinet where airflow is controlled. Additional functional safety hardware is not present, so external contactors or safety relays must be added when emergency-stop performance levels are required.
