Product Description:

The EFC5610-0K75-1P2-MDA-7P-NNNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. Designed for panel mounting inside control cabinets, it converts fixed mains voltage into a variable output for small AC motors used in conveyors, fans, and other general-purpose machinery. By modulating both frequency and amplitude, the unit supports precise speed adjustment, improved energy use, and steadier process control. Its compact footprint also suits machine layouts where cabinet space is limited and a full-size drive would be unnecessary. It is suitable for applications that need repeatable motor response across changing loads, such as simple transport systems or small process stations.

This model accepts an input of 200–240 V AC with a tolerance of ±10%. From that supply, it can deliver up to 0.75 kW of heavy-duty motor power for small machines that still need controlled acceleration and stable running speed. It uses standard vector control (SVC), so torque remains steady at low speed without external feedback. An EMC stage rated for class C3 limits conducted emissions, and Safe Torque Off (STO) removes drive energy during an emergency stop. The standard control configuration includes Flex-Control I/O with eight digital inputs, two digital outputs, and analog terminals for routine machine signals. This arrangement supports common start-stop commands, speed references, and status signaling without requiring additional control hardware at the outset.

Parameter access is handled through a standard LCD display with potentiometer, so local setup can be done without an external keypad. For higher-level supervision, the converter communicates via Modbus over RS-485, allowing register-based control from many PLCs and similar controllers. The power stage is arranged for single-phase operation, and the housing has IP20 protection, so the unit must be mounted inside a closed panel. That enclosure placement helps protect the drive from direct contact and airborne contamination in open machine areas. Using the front display also allows quick parameter review when cabinet access is available.
