Product Description:

The EFC5610-5K50-3P2-MDA-7P-NNNNN-L1NN is a variable-speed frequency converter manufactured by Bosch Rexroth Indramat and supplied within the EFC Frequency Converters series. It regulates the speed and torque of induction motors used in machinery and process equipment on factory floors, allowing motor output to track changing load demand. The unit is intended as a general-purpose drive for installation in automation cabinets where compact motor control and standard operator access are required.

It accepts a three-phase input of 200 V AC (200 to 240 V ±10%), enabling connection to low-voltage plant mains. The power section delivers a heavy-duty motor output of 5.5 kW, which suits conveyor, pump, or fan loads. Line supply is connected through three phases, and enclosure sealing is rated at IP 20, so installation is limited to clean, ventilated panels. Internally, the controller uses the Flex-Control with Standard I/O design, which provides discrete terminals for start, stop, and speed reference signals. Operating parameters are entered on a standard LCD display with an integrated potentiometer, and the control configuration is standard for Product Line 02. The built-in Safe Torque Off circuit disconnects the power stage to help prevent unintended shaft rotation when the safety input is active.

Communication is provided through the Modbus interface, allowing higher-level PLCs to read status words and issue frequency commands over a two-wire link. Speed regulation is handled by Standard Vector control SVC, which supports stable torque production at low frequencies without encoder feedback and improves low-speed motor behavior in variable-load applications. To meet plant emission limits, the drive includes an EMC filter for industrial area, class C3 environments, helping keep conducted interference within permitted industrial levels. The housing uses Frame Size F, which provides mounting points that match the mechanical layout used for this frame. This layout supports consistent panel spacing and helps the drive fit cabinets designed for the same size class.
