Product Description:

The EFC5610-3K00-3P2-MDA-7P-DRNNN-L1NN is a frequency converter built by Bosch Rexroth Indramat for the EFC Frequency Converters series. It belongs to the EFC 5610 line, where it is listed as product line 02 and frame size E. In an automation cell, the unit converts fixed mains power into variable voltage and frequency output so asynchronous or synchronous motors can be matched to the process load. This supports energy-saving speed control on pumps, fans, and material-handling drives without requiring a separate motor starter for routine speed adjustment.

For power compatibility, the converter accepts a three-phase input of 200–240 V AC ±10%, and its heavy-duty rating supports up to 3.0 kW of motor power without derating. Torque regulation is handled by standard vector control (SVC), so the drive can keep motor flux optimized during low-speed operation. Network integration is available through Modbus, which allows parameter access from PLCs or HMIs. To reduce conducted emissions, the integrated EMC filter is classified for industrial area, Class C3. The control section uses Flex-Control architecture with standard I/O, and the standard configuration provides discrete terminals for run, direction, and fault reset commands.

Operator interaction occurs through a standard LCD display with potentiometer, allowing local setpoint entry and real-time status monitoring without separate interface hardware. The unit is wired to a three-phase supply and is housed in an enclosure rated IP20, so it must be installed inside a cabinet for touch-safe operation. When machine safety is required, the built-in Safe Torque Off (STO) circuit disables power to the motor within the drive, removing torque-producing energy without external contactors. This arrangement supports straightforward local control while leaving room for higher-level commands through the communication and terminal interfaces.
