Product Description:

The EFC5610-1K50-3P4-MDA-7P-NNNNN-NNNN frequency converter produced by Bosch Rexroth Indramat belongs to the EFC Frequency Converters series. It is intended to vary the speed of standard induction motors in automated machinery by modulating the supplied voltage and frequency. As a component of drive cabinets or distributed motor control centers, the unit provides vector-based speed regulation so pumps, fans, or material-handling axes can match process demands instead of running at fixed mains frequency. This helps the connected motor operate only at the speed needed for the task.

Under heavy-duty loading, the inverter can deliver 1.5 kW of mechanical output at the motor shaft. It is powered from a 400 V utility network with an input range of 380 to 480 VAC. Internally, the unit converts that three-phase input to a PWM output that still supports three phases at the motor terminals. Speed and torque are computed with standard vector control (SVC), allowing closed-loop current regulation without encoder feedback. For electromagnetic compatibility, the integrated filter is rated for industrial area class C3, so additional line reactors are normally unnecessary in production environments subject to C3 emission limits. The design follows the Flex-Control concept and provides standard digital and analog I/O for start, stop, and reference signals.

Field integration relies on the embedded Modbus interface, enabling parameter access and run commands from a PLC over a two-wire RS-485 link. Operators can review setpoints and alarms through the standard LCD display with a potentiometer mounted on the front panel, which also offers local speed trimming. The plastic housing meets IP20, so it must be installed inside a controlled enclosure, and its compact frame size C simplifies retrofits where cabinet space is limited. No dedicated safety function is included, so any required STO or emergency-stop circuit must be provided externally.
