Product Description:

Bosch Rexroth Indramat manufactures the EFC5610-5K50-3P4-MDA-7P-NNNNN-L1NN frequency converter for variable-speed control of induction motors in automated machinery. The unit belongs to the EFC Frequency Converters series and is part of product line 02. It is intended for cabinet-mounted motor control in pumps, fans, conveyors, and other machine functions that require adjustable speed. By modulating output frequency and voltage, it adjusts motor operation to match process demand rather than running continuously at a fixed speed. Its Flex-Control section with standard I/O accepts discrete start, stop, and speed-reference signals without add-on hardware.

Incoming power is accepted at 400 V AC (380…480 V −15 % / +10 %), and communication with higher-level controllers occurs through the Modbus interface for integration with plant control systems. In heavy-duty service, the converter supplies 5.5 kW of motor power and uses Frame Size E for a predictable cabinet footprint and mounting space. The housing has an IP 20 rating, which helps protect internal parts while still allowing convection cooling in enclosed panels. For functional safety, the hardware includes Safe Torque Off (STO), which removes torque-producing power from the motor. The front panel uses a standard LCD display with an integral potentiometer, so operating values and basic settings can be adjusted locally without extra accessories.

The built-in filter meets Industrial area, class C3 requirements and is intended for use on a three-phase supply network. Inside the drive, flux is calculated by the Standard Vector control SVC algorithm, so the motor can maintain steady torque from low speed to base speed without an encoder. During a safety stop, the output stage is disabled and the motor coasts, while normal operation continues to benefit from filtered input power and stable vector-based control. This arrangement supports consistent motor response in applications that cycle between acceleration, steady running, and controlled stopping.
