Product Description:

The EFC3610-11K0-3P4-MDA-7P-00002-NNNN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. It belongs to product line 02. In automated plants, the unit sits between the mains supply and an induction motor, varying the applied frequency so that machine speed, torque, and energy use can be matched to process demands without mechanical gear changes.

Plant networks access parameters through the built-in Modbus link, eliminating separate gateway hardware. The power section accepts a nominal 400 V input over three-phase 380 to 480 V lines. Using a three-phase supply ensures balanced current draw and lower conductor demand compared with single-phase drives. Motor voltage is modulated by Enhanced V/Hz control, which keeps a constant volts-to-hertz ratio so rated torque is available from standstill to base speed. An integrated EMC filter identified as Industrial area, class C3 restricts conducted emissions on long motor leads typical of factory installations. Standard control configuration and the Flex-Control section with standard I/O provide screw terminals for run, direction, fault reset, and 0 to 10 V or 4 to 20 mA speed reference signals.

Under heavy-duty loading, the inverter delivers 11.0 kW of output power, allowing it to drive 15 HP motors without derating. All components are arranged in frame size F, giving a consistent mounting footprint across the series and simplifying cabinet layouts. The housing carries an IP20 protection class, so the converter must be installed inside a closed panel to prevent accidental contact while still benefiting from unrestricted airflow. Local operation is handled through a standard LCD display with potentiometer, which shows operating status and allows direct speed adjustment without fieldbus access. The model’s design omits integrated safety functions, leaving emergency-stop provisions to external contactors as required by the application and relevant standards.
