Product Description:

The EFC5610-2K20-3P4-MDA-7P-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series and is part of product line 02. As an AC drive, it regulates induction motor speed and torque so production equipment can match process demand while reducing energy use. The unit is intended for installation in standard control cabinets where indoor conditions are controlled and airborne contamination is limited.

This model operates on a mains circuit rated for AC 380–480 V and delivers a heavy-duty motor output of 2.2 kW. Speed regulation is handled through standard vector control (SVC), giving constant torque across a wide frequency span. System communication is available through Modbus, enabling simple integration into PLC networks. The converter housing meets IP20, so ventilation openings remain unsealed and the device must be mounted inside a suitable enclosure. Control components use the standard configuration and the Flex-Control section with standard I/O to support typical start, stop, and feedback signals, while a standard LCD display with an integrated potentiometer provides local parameter entry and real-time operating data.

Functional safety is addressed by the certified Safe Torque Off (STO) input that disables power to the motor without mechanical contactors. Conducted emissions are limited by an EMC filter rated for the industrial area, Class C3, allowing installation in heavy-industry switchboards. The converter uses frame size D, so its mounting hole pattern, heat sink length, and cable cross-sections match that housing size. The power stage is designed for three-phase operation and uses a standard rectifier-inverter topology to supply the motor. The device is intended for clean, indoor automation areas with filtered airflow and controlled ambient temperatures.
