Product Description:

The EFC5610-0K40-1P2-MDA-NN-NNNNN-L1NN frequency converter belongs to the EFC Frequency Converters series from Bosch Rexroth Indramat. It is designed to vary the speed of small AC induction motors in automated conveyors, dosing units, and similar machines by generating a controlled output frequency from a fixed mains supply. Integrating this device removes the need for separate drive electronics while providing a compact source of motor speed regulation in industrial automation.

The converter communicates through Modbus, allowing a PLC to issue commands and collect status data over a serial line. Internally it uses standard vector control (SVC), so the motor can develop rated torque even at low shaft speeds without encoder feedback. Under heavy-duty conditions, the power stage supports motors rated at 0.4 kW, covering many light mechanical loads. The input circuit accepts 200–240 V AC (±10%), rectifies it, and maintains a stable DC link without an auxiliary transformer. Its open-chassis housing meets IP20, so it is intended for installation inside a protected control cabinet where basic finger-safe shielding is required.

Functional safety is provided by Safe Torque Off (STO), enabling removal of motor torque through a hardwired signal without software intervention. Conducted and radiated emissions are limited by an EMC filter classified for Industrial area, class C3, making the unit suitable for factories with existing electromagnetic noise. Power terminals are arranged for a single-phase supply, and thermal dissipation is matched to the mechanical envelope identified as frame size B. A Flex-Control section with standard I/O covers basic start-stop logic, the model is indexed within product line 02, and a dust cover replaces a local keypad so the unit can operate without on-panel programming.
