Product Description:

The EFC5610-3K00-3P4-MDA-7P-NNNNN-L1NN is a cabinet-mounted frequency converter built by Bosch Rexroth Indramat for the EFC Frequency Converters series. It is intended to regulate induction motor speed in automated conveyors, mixers, and pump modules used across manufacturing cells. By supplying a variable output frequency, the unit lets controllers match shaft speed to actual load, which improves process consistency and can reduce energy drawn from the mains. This type of control is useful when process demand changes during normal operation, because the motor does not need to run at full speed all the time.

The converter accepts a three-phase input of 380–480 V AC and can drive motors rated for 3.0 kW in heavy-duty service. An integrated EMC filter rated for Industrial area, class C3 limits conducted noise so the drive can be installed near sensitive control equipment without additional chokes. For enclosure protection, the housing meets IP20, which helps protect against accidental finger contact while leaving ventilation open to the control cabinet environment. Safety is supported by the hardware-based Safe Torque Off (STO) circuit, which removes gating signals to the power stage and helps prevent unintended restart during maintenance or emergency stops. The wide input range also helps the same model fit common industrial supply systems without changing the drive platform.

The unit communicates with higher-level PLCs through Modbus, so it can integrate into existing fieldbus networks without proprietary gateways. Motor regulation is handled by standard vector control (SVC), allowing steady torque delivery from zero speed upward across common process loads. The mechanical layout follows frame size D, which standardizes mounting hole patterns and airflow spacing inside multi-drive panels. Power is drawn from a three-phase supply, and the Flex-Control section provides standard I/O terminals for run, fault, and analog speed references. A backlit LCD with an integral potentiometer gives local access to parameters and operating values. The local interface can also be used to review status messages, adjust operating values, and move through menus directly at the front of the unit.
