Product Description:

The EFC5610-45K0-3P4-MDA-7P-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. It belongs to the EFC 5610 model group and product line 02, and it connects between a facility’s three-phase mains supply and an AC motor. By varying output frequency and voltage to match demand, the unit helps control motor speed in conveyors, pumps, and material-handling axes. This operating method supports smoother process response during changing loads and can reduce unnecessary mechanical stress during routine machine operation.

The converter accepts a three-phase supply rated at 400 V, with an operating tolerance of 380 to 480 V and a line tolerance of -15% to +10%. Under heavy-duty conditions, it delivers up to 45.0 kW to the connected motor. Speed regulation is handled by standard vector control (SVC), which supports stable torque at low frequencies without requiring external sensors. A Flex-Control section with standard I/O is included with the standard control configuration, and supervisory communication is handled through Modbus for remote start, stop, and diagnostic access. The housing is rated IP 20, so the unit is intended for cabinet mounting while still providing basic protection against accidental contact with live parts.

The built-in EMC filter is rated for industrial areas, class C3, which helps limit conducted emissions in suitable industrial installations. Its mechanical format follows Frame size I, setting the mounting footprint and cable entry arrangement for the unit. Local operation uses a Standard LCD display with potentiometer, allowing parameter entry and manual speed adjustment from the front of the drive. Functional safety is provided by Safe Torque Off (STO), which removes gate signals to the power stage in less than 1 ms. This arrangement allows the drive to be integrated into applications that require controlled shutdown of motor torque without adding a separate external switching device for that function.
