Product Description:

The EFC5610-1K50-3P2-MDA-7P-DRNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat in the EFC Frequency Converters series. It modulates the voltage and frequency supplied to an induction motor so that machine speed can be adjusted to match process demand. This supports controlled operation in conveyors, mixers, and process pumps, where stable motor response and efficient speed regulation are important during changing load conditions.

Control functions are handled by the Flex-Control section with Standard I/O, which allows direct connection of local sensors and actuators without extra interface modules. Parameter access and remote commands are available through Modbus, making it easier to link the converter with plant control systems. The converter uses Standard Vector control SVC to maintain steady torque over a broad speed range without requiring external encoder feedback. It is designed for 200 V (AC 200...240 V +/- 10%) service on a three-phase line, matching common industrial power systems. An internal filter rated for class C3 for industrial areas helps reduce conducted emissions when the drive is installed near other electrical equipment.

User interaction is provided by a standard LCD display with a potentiometer, and the control setup remains standard for routine parameter entry and monitoring. Within frame size C, the power section is rated for a heavy-duty motor output of 1.5 kW, which gives the unit a compact format for panel mounting while still supporting typical low-voltage drive duties. The housing has an IP20 protection rating, so it is intended for installation inside a control cabinet rather than open exposure on the machine. Functional safety is provided by Safe Torque Off (STO), which disables torque-producing energy through hardware channels when a stop function is required.
