Product Description:

The EFC5610-5K50-3P4-MDB-7P-NNNNN-L1NN frequency converter is produced by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. It accepts fixed-frequency mains power, converts it through an internal DC link, and delivers a variable output that lets three-phase motors accelerate, decelerate, or hold speed precisely in automated material-handling, HVAC, and packaging lines. The device acts as the regulating element between the utility supply and the motor shaft, reducing inrush current and permitting application-specific speed profiles.

The converter is designed for a nominal input of 400 V (AC 380…480 V −15 % / +10 %) across three phases, so it can be wired directly to common industrial low-voltage grids without an autotransformer. Under heavy-duty loading, it supports motors up to 5.5 kW, enabling direct control of mid-sized pumps or fans. Communication takes place over Modbus, giving a straightforward register map for parameter access from PLCs or SCADA nodes. Vector algorithms identified as Standard Vector control SVC adjust flux and torque in real time, yielding stable speed even when the load varies. An internal EMC filter rated for Industrial area, class C3 suppresses conducted emissions so the installation remains compliant with electromagnetic compatibility requirements in motor-control cabinets.

Mechanical integration is simplified by the converter’s IP 20 Cold Plate housing, which transfers heat to an external mounting surface and permits cabinet airflow planning without a dedicated fan inside the unit. Functional safety is addressed through Safe Torque Off (STO); when the STO terminals open, drive output is inhibited for safety-related machinery without reliance on contactors. The enclosure follows Frame Size E dimensions, keeping depth and mounting-hole pattern consistent across the 5610 product line. A Standard LCD display with potentiometer on the front panel lets users view status words, edit parameters, and jog the connected motor locally.
