Product Description:

The EFC5610-7K50-3P4-MDA-7P-DRNNN-NNNN frequency converter is manufactured by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. Within industrial automation systems, it functions as a variable-speed drive by adjusting motor frequency and voltage to match process demands. By varying output frequency instead of applying full line power directly to the motor, the unit supports smoother starts and more stable process control. It is intended for applications that need adjustable motor speed rather than fixed full-line operation. The product is categorized in the EFC 5610 line and in product line 02, so it fits installations that need a compact converter for general-purpose motion on 400 V factory power grids.

This model accepts a nominal supply of 400 V (AC 380…480 V -15 % / +10 %) across three phases, giving it compatibility with common low-voltage distribution networks. The stated input range also allows the converter to operate with plant supplies that vary within normal tolerance limits. It can deliver up to 7.5 kW of motor power in heavy-duty service. Torque production is controlled through standard vector control SVC, which maintains speed accuracy under changing loads without external encoders. This helps the converter respond to load changes in general industrial equipment without excessive speed droop. An integrated industrial area class C3 EMC filter attenuates conducted noise so the converter can operate in industrial zones. The unit keeps a standard control configuration and uses a Flex-Control section with standard I/O, meaning discrete signals and analog references can be wired directly to the terminal strip without option cards.

The drive uses a Frame Size E housing, and the enclosure carries an IP20 protection class for cabinet installation with finger-safe access. Parameterization and local jogging are handled by a Standard LCD display with potentiometer, while networked supervision is possible through the built-in Modbus communication port. The front keypad also allows direct review of status values during routine machine operation. No certified safety function is provided, so emergency stop or STO must be implemented externally. The design omits braking choppers and additional onboard safety hardware.
