Product Description:

The EFC5610-3K00-3P4-MDB-NN-FCPNN-NNNN frequency converter is manufactured by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. In automated lines, this unit feeds variable-frequency power to induction motors, letting controllers tune shaft speed without mechanical gear changes. It forms the link between the plant’s fixed-frequency mains and the load, providing soft starts, controlled acceleration, and energy-saving operation for conveyors, pumps, and similar equipment. By varying output frequency and voltage, it helps motor-driven equipment respond more smoothly to changing process demand and reduces mechanical stress during startup.

Incoming power must lie within 400 V (AC 380 to 480 V -15% / +10%), and the device uses three-phase power, so it connects directly to common low-voltage supplies. Torque is regulated by standard vector control (SVC), which maintains motor flux at low speed for constant torque. Network communication is handled through Modbus, enabling parameter access from PLCs without optional cards. The mechanical footprint follows frame size D, giving a cabinet depth compatible with the D-class of the EFC 5610 platform. A dust cover replaces a local keypad, so adjustments require remote access or temporary cover removal. Because no safety function is integrated, external equipment must perform any STO or SS1 tasks.

Under heavy-duty ratings, the converter supplies 3.0 kW to the motor. Heat is removed through its IP20 cold-plate housing, which conducts thermal energy to the mounting surface instead of using fans. Conducted emissions are limited by an internal filter certified for industrial area, Class C3, supporting installation in general industrial zones. All command, feedback, and relay terminals are grouped in the Flex-Control with standard I/O section, which offers eight digital and two analog channels for basic standalone logic. That layout supports simple interlocks, run commands, and status handling without extra interface modules.
