Product Description:

The EFC5610-5K50-3P4-MDA-7P-DRNNN-L1NN is a variable-speed frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. Classified under product line 02 and the EFC 5610 model family, it converts fixed-frequency mains power into a modulated output for induction motors used in conveyors, pumps, and other automated machinery. Its Flex-Control section with standard I/O supports stand-alone operation or networked control, allowing process speed and torque to match load requirements without mechanical gear changes.

The drive operates on a nominal 400 V supply that may vary between 380 V and 480 V, so it can be installed on typical low-voltage industrial feeders without a step-down transformer. It is wired for three phases, enabling balanced current flow and reduced harmonic distortion compared with single-phase solutions. In heavy-duty cycles, the inverter delivers 5.5 kW of mechanical output, supplying reserve capacity for pumps or compressors that draw high starting torque. Motor flux is regulated by Standard Vector control SVC, which helps maintain commanded speed when load fluctuates. An internal EMC filter rated for Industrial area, class C3 limits conducted emissions so the unit is suited for industrial installations.

Communication uses Modbus, letting PLCs or HMIs read parameters and issue commands without proprietary hardware. Operating data appear on the front Standard LCD display with potentiometer, which also provides a local frequency setpoint when direct adjustment at the drive is needed. The safety circuit includes Safe Torque Off (STO), which removes torque-producing power to the motor without opening the mains contactor. The housing carries an IP 20 rating, giving finger-safe protection when the converter is mounted inside a closed panel. Frame size E and the standard control configuration help maintain airflow clearances while keeping cabinet width moderate.
