Product Description:

The EFC5610-110K-3P4-MDA-7P-FCPNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. Classified under product line 02 and model series EFC 5610, the unit is installed between a three-phase power source and an AC motor to provide variable-frequency output for speed and torque regulation in automated equipment. By converting fixed utility power, it supports energy-efficient control of conveyors, pumps, compressors, and similar loads in general manufacturing environments. It is commonly used where smooth acceleration and adjustable speed are needed across changing load conditions.

It operates from a nominal input of 400 V (380–480 V, −15% / +10%) and, in heavy-duty service, can drive motors up to 110.0 kW. A symmetrical supply of Three phases balances line current, and the Standard Vector control SVC algorithm helps maintain stable torque at low speed. Communication through Modbus transfers parameters and diagnostic data to PLC networks, while the integrated EMC filter for industrial areas class C3 reduces conducted emissions on long cable runs. The control section uses the Flex-Control layout with standard I/O and ships in a standard control mode.

The front panel uses an LCD display with an integral potentiometer so local setpoints and status values can be viewed without extra accessories. An enclosure rating of IP 20 means the frame size K converter is intended for cabinet installation, where the housing is protected from accidental contact while still allowing cooling airflow. For personnel protection, the Safe Torque Off function STO interrupts gate drive to the output stage through dual channels, allowing the machine to remove torque without external contactors. This feature supports controlled shutdown behavior in systems that require a safety-related stop response.
