Product Description:

The EFC5610-75K0-3P4-MDA-7P-SVPNN-L1NN frequency converter is produced by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. It links the incoming mains supply to an AC motor by varying output frequency and voltage so the driven equipment can run at the speed required by the process. This makes it suitable for conveyors, pumps, and fans that need adjustable motor control during normal plant operation. By adjusting motor speed electrically, the drive can reduce mechanical stress during startup and match flow or throughput more closely than fixed-speed operation.

The converter accepts a supply of 400 V (AC 380 to 480 V, -15% / +10%) and, in heavy-duty mode, can deliver up to 75.0 kW of mechanical power. A Flex-Control section with standard I/O handles digital and analog commands, and the unit uses a standard control configuration. Torque output is managed through a three-phase bridge with vector regulation, which helps keep current balanced during load changes. Integrated functional safety is provided by Safe Torque Off (STO), which removes gate signals to the IGBTs within milliseconds. For electromagnetic compatibility, an internal filter rated Industrial area, class C3 reduces conducted interference in industrial panels.

Parameters can be entered through the built-in LCD interface with a potentiometer and through the Modbus port, allowing higher-level control systems to read status and operating data. Precise speed regulation relies on Standard Vector control SVC, which maintains motor flux without encoder feedback and supports stable operation across changing loads. The local display also supports quick parameter review and basic status checks at the cabinet door. The housing uses Frame Size J proportions, and its terminals are arranged for straightforward top-entry wiring inside the cabinet. A protection rating of IP20 allows installation in ventilated enclosures where contact with live parts is restricted and exposure to water is not expected.
