Product Description:

The EFC5610-5K50-3P4-MDA-7P-NNNNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. The unit functions as an open-loop and vector speed controller for induction motors used in conveyors, pumps, and material-handling cells. By varying output frequency to match process demand, it reduces energy consumption and mechanical stress while supplying the torque profile required for industrial duty cycles. It also fits easily into cabinet layouts because of its compact frame and standard wiring pattern.

The converter accepts a 400 V (AC 380...480 V -15% / +10%) mains supply and is wired for three-phase power, so it connects directly to common factory distribution panels. In heavy-duty service, it drives motors up to 5.5 kW, and the power stage is managed by standard vector control (SVC) that maintains torque at low speed without encoder feedback. Command and diagnostic exchanges use Modbus, enabling a PLC to adjust parameters or read status over a single RS-485 channel. Flex-Control with Standard I/O provides discrete run, fault, and analog speed terminals for stand-alone installations where fieldbus is not present. The converter supports variable-torque loads that start under load or require rapid acceleration.

Ingress protection is rated at IP 20, so the unit must be installed inside a control enclosure. The integral EMC filter meets industrial area, Class C3 limits, reducing conducted emissions on long motor cables. Mechanical dimensions correspond to Frame Size E, which helps when fitting the unit into existing E-frame panels. Local operation is handled through a standard LCD display with potentiometer, which lets operators set speeds or view alarms without external software. Additional attributes include a standard control configuration, a Flex-Control section design, and product line code 02.
