Product Description:

The EFC5610-110K-3P4-MDA-7P-DRNNN-L1NN is a variable-frequency drive manufactured by Bosch Rexroth Indramat and assigned to the EFC Frequency Converters series. As a component of automated machinery, it modulates the speed and torque of squirrel-cage induction motors so that process lines run at the required throughput while minimizing energy use. This helps production equipment respond to changing load conditions instead of operating at a fixed motor speed. It is part of the EFC 5610 range and is suitable for industrial applications such as conveyors, pumps, fans, and similar variable-speed systems.

The drive operates on a nominal input of 400 V (AC 380…480 V -15 % / +10 %) supplied through a three-phase mains connection. With frame size K, the unit fits cabinet layouts intended for that mechanical format and keeps the mounting arrangement consistent with other drives of similar size. The standard vector control (SVC) mode regulates motor torque without an external encoder and allows the converter to support up to 110.0 kW of heavy-duty motor power. The control section includes standard digital and analog I/O for routine command handling, and the LCD keypad with a potentiometer allows local adjustment when direct access to operating parameters is needed.

The housing has an IP20 rating, so the unit is intended for installation inside a clean electrical enclosure with forced convection. A built-in Safe Torque Off (STO) circuit removes torque-producing output when the safety relay is triggered, while Modbus communication exchanges run status, fault codes, and setpoints with PLCs over an RS-485 network. The converter also includes an industrial area, class C3 EMC filter to limit conducted emissions in industrial installations. These functions support safe operation, stable communication, and reduced electrical interference during normal machine use.
