Product Description:

The EFC5610-5K50-3P4-MDA-7P-00002-L1NN is a frequency converter built by Bosch Rexroth Indramat within the EFC Frequency Converters series. It is used in industrial automation to control the speed of three-phase motors by converting fixed-frequency mains power into a variable-frequency output that matches process requirements. The unit is commonly installed on conveyor, pump, and fan systems where adjustable motor speed helps match machine output to the demands of the process.

The converter has a heavy-duty rating of 5.5 kW, so it can continuously supply this power level to a connected motor when the load profile falls under heavy-duty operation. Its input supply is based on 400 V AC and accepts a range from 380 to 480 V with a tolerance of -15% to +10%, which helps it accommodate common factory power variation. Speed control is handled through Standard Vector control SVC, which maintains motor torque by calculating motor flux in real time. Communication is available through Modbus, allowing parameter access from a PLC or HMI. The enclosure has an IP20 protection class, so it provides protection against contact with internal parts and is intended for cabinet installation.

A certified Safe Torque Off (STO) channel removes drive energy during an emergency stop, allowing torque production to be interrupted by the safety circuit without external contactors. The mechanical layout uses frame size E, so the mounting pattern and housing depth match other E-frame units in the product line. Conducted emissions are reduced by the integrated Industrial area, class C3 EMC filter, which helps limit high-frequency noise on power lines. A standard LCD display with potentiometer allows local adjustment of acceleration ramps and setpoints. It also uses the Flex-Control section with standard I/O, a three-phase output topology, the EFC 5610 model designation, a standard control configuration, and product line code 02.
