Product Description:

The EFC5610-1K50-3P4-MDA-7P-DRNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. As part of the EFC 5610 line in product line 02, it supplies variable-speed control for three-phase induction motors used in conveyors, pumps, and compact machine modules. By modulating output frequency and voltage, it allows process equipment to match load demand, conserving energy and reducing mechanical stress during acceleration and deceleration.

The drive accepts a rated mains supply of 400 V (380–480 V AC, −15% / +10%) on a three-phase supply, ensuring stable operation on utility feeds that deviate from nominal values. Inside the inverter, it uses standard vector control (SVC), which calculates real-time current vectors so torque remains steady even without feedback devices. In heavy-duty mode, the unit supplies 1.5 kW to the motor, supporting intermittent overloads typical of starting centrifugal loads. Conducted emissions are suppressed by the integrated Industrial area, class C3 EMC filter, which helps meet plant-wide electromagnetic compatibility targets and may eliminate the need for an external line filter.

The control hardware follows the standard configuration and uses a Flex-Control section with standard I/O for direct wiring of sensors, relays, and analog references. Its compact frame size C housing simplifies cabinet layouts shared with other drives in the range. Networked supervision is available through a built-in Modbus port that exposes parameters to common PLC platforms. Functional safety is handled by Safe Torque Off (STO) terminals that remove power to the motor when signaled, avoiding separate contactors. The converter carries an IP20 ingress rating. A front-mounted LCD display shows operating data, and a built-in potentiometer allows local speed adjustment.
