Product Description:

The EFC5610-3K00-3P4-MDB-7P-NNNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It sits in the EFC 5610 model series and in product line 02 of the low-voltage drives portfolio. In automated plants, the converter provides variable-speed control for induction motors, allowing the drive to match torque and speed to process demands without mechanical gear changes. This helps the connected motor respond smoothly to changing load and speed requirements during normal operation. The unit is installed between the mains supply and the motor terminals to modulate output frequency and voltage.

The converter operates from a 400 V AC input (380 to 480 V, -15% to +10%) and delivers 3.0 kW of output in heavy-duty mode, matching small pumps, fans, and conveying axes. Frame size D sets its mechanical envelope, and the cold-plate housing can be bolted directly to a chilled panel. An internal filter with an industrial area, class C3 rating limits conducted emissions on the mains, while the enclosure has an IP 20 Cold Plate protection class that shields live parts and relies on the mounting surface for heat dissipation. This arrangement suits enclosed panels that use the backplate as the main thermal path. The safety circuit provides Safe Torque Off (STO) to de-energize the power stage when an external stop channel is asserted. Standard control configuration and the Flex-Control section with standard I/O provide fixed terminals for run, direction, and fault signals.

Parameter access is handled by the standard LCD display with potentiometer, so reference speed can be trimmed without opening the cabinet. Drive commands and diagnostics can also be exchanged over Modbus, enabling integration with PLCs that do not require additional fieldbus cards. Closed-loop flux regulation is carried out by standard SVC vector control, providing stable torque at low speed without encoder feedback. The power stage is designed for three-phase power only, preventing single-phase misapplication. The Flex-Control board also carries serial and logic ports for digital I/O mapping.
