Product Description:

The EFC5610-7K50-3P2-MDA-7P-DRNNN-L1NN is a member of the EFC Frequency Converters series manufactured by Bosch Rexroth Indramat. As a universal AC drive, it provides adjustable speed control for induction motors in conveyors, pumps, and general automation. The unit belongs to the EFC 5610 product line and uses the Flex-Control platform, allowing direct panel or PLC operation through standard I/O. By converting fixed mains voltage to a variable output frequency, the converter manages motor torque and energy use in industrial processes.

Mains supply compatibility spans a nominal 200 V to 240 V AC ±10%, so the drive can be connected to low-voltage factory networks without an isolation transformer. It is designed for three phases, which helps provide balanced current flow and reduced harmonic stress on the grid. Motor regulation is handled by standard vector control SVC; this algorithm maintains stable torque even at low speed by monitoring voltage and current vectors in real time. In heavy-duty mode, the converter supports up to 7.5 kW of motor power, enabling direct startup of medium-sized pumps or blowers without external soft starters. An integrated EMC filter rated for Industrial area, class C3 attenuates conducted noise so the installation meets emission limits in machine rooms and production halls.

The housing carries an IP 20 protection class, which prevents contact with live parts when the unit is mounted inside a control cabinet. Parameter access is provided through a standard LCD display with potentiometer, allowing operators to set acceleration ramps or view fault codes without a separate programming console. For remote supervision, the converter uses Modbus, allowing simple register mapping over RS-485 for start, stop, and diagnostics. A built-in safety input activates Safe Torque Off (STO); when triggered, it removes gate signals to the output stage so motor torque falls to zero without relying on mechanical relays.
