Product Description:

The EFC5610-2K20-1P2-MDB-7P-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat and supplied within the EFC Frequency Converters series. In plant automation, the unit modulates the voltage and frequency delivered to an asynchronous motor so speed, torque, and energy consumption can be matched to process demands. It is suited for variable-speed duties such as conveyor movement, pump control, and fan service where compact drive hardware is needed in a control cabinet.

The converter operates from a mains supply of 200 V AC (200–240 V ±10%), a range suited for regional low-voltage networks. Its heavy-duty rating provides 2.2 kW of mechanical output, indicating the maximum continuous motor shaft power it can support without derating. A single-phase input design allows connection to common utility feeds while the internal DC link synthesizes a balanced three-phase output for the motor. Speed regulation is handled by Standard Vector control (SVC), and this control method helps maintain torque at low frequencies and during load swings. Electrical noise conduction is limited by the integrated class C3 EMC filter, permitting installation in industrial zones with tighter emission limits.

Mechanical layout follows frame size D with an IP20 cold plate housing that relies on external panel cooling, which keeps overall depth small and supports installation in populated cabinets. Functional safety is addressed through Safe Torque Off (STO), which removes drive energy to the motor in emergency-stop circuits without additional contactors. Control integration uses Modbus for parameter access and diagnostic polling over standard serial lines. Local setup is simplified by an LCD display with potentiometer, allowing parameter changes and setpoint adjustment without external tools. This arrangement supports routine operation where the drive must be adjusted directly at the cabinet.
