Product Description:

The EFC5610-75K0-3P4-MDA-7P-NNNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. As a variable-speed drive component, the unit modulates the power delivered to induction motors so conveyor sections, pumps, and other equipment can operate at controlled speeds or follow programmed ramps. It belongs to the EFC 5610 model range, is part of product line 02, and uses a standard control configuration with a Flex-Control section that provides conventional digital and analog I/O for general-purpose automation. This layout supports common machine functions without requiring a specialized feedback package for routine speed control tasks.

The power stage supports heavy-duty motors up to 75.0 kW. It accepts a nominal supply of 400 V AC over a three-phase supply, matching typical industrial feeders across the stated input range. Closed-loop torque and speed regulation are handled by standard vector control (SVC), which helps maintain stable motor rotation at low frequencies without an encoder. Remote parameter access, diagnostics, and run commands are available through the built-in Modbus communication channel. Frame size J sets the mechanical envelope and mounting points for cabinet installation.

The converter housing is rated at IP20, so it is intended for installation inside a protective enclosure that provides suitable airflow. Conducted emissions are limited by an integrated EMC filter classified as industrial area, Class C3, which suits typical plant power systems and reduces the need for external suppression in many installations. For functional safety, a hardware-based Safe Torque Off (STO) circuit removes torque-producing output when the enable signal is withdrawn, helping prevent unintended motor movement. Operation and parameter entry are handled from a front panel with a standard LCD display with potentiometer, giving local access to status information and speed adjustment.
