Product Description:

The EFC5610-2K20-3P4-MDA-NN-NNNNN-L1NN is a compact frequency converter produced by Bosch Rexroth Indramat for the EFC Frequency Converters series. It regulates the speed of three-phase induction motors in conveyor sections, pumps, and other automated equipment where adjustable torque and stable motor response are needed. The unit is part of product line 02 and is intended for cabinet-based installations that need a compact drive format. By varying output frequency and voltage, it lets the connected motor follow process demand more closely than a fixed-speed starter.

The inverter communicates with controllers through Modbus, allowing basic parameter access without a dedicated fieldbus option. Its standard vector control (SVC) algorithm helps maintain stable motor flux as load conditions change, and this supports smoother operation during acceleration and deceleration. The mains input is rated at 400 V AC and operates across a 380 to 480 V range with a tolerance of -15% to +10%. Power is supplied through a three-phase supply, and in heavy-duty operation the drive supports motors up to 2.2 kW. The unit uses frame size D for its enclosure, and the standard configuration has no keypad, so a dust cover protects the display opening on the front panel.

The control section uses Flex-Control with standard I/O, which provides digital and analog signal handling for common machine commands and status points. The available I/O can be used for run commands, status outputs, and reference signals in standalone systems or simple networked installations. An integrated filter rated for industrial area, Class C3 helps limit conducted emissions on plant power lines. The enclosure has an IP20 protection class, so it is suited for panel mounting inside a cabinet rather than direct exposure on the machine. Functional safety is provided by Safe Torque Off, which disables gate signals to the output stage when a stop command is triggered.
