Product Description:

The EFC5610-2K20-3P4-MDA-7P-DRNNN-L1NN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. Serving as the interface between the mains supply and an induction motor, it modulates voltage and frequency so automated equipment can match speed and torque to process demand. This control method helps the motor run at the speed required by the application instead of operating at a fixed line frequency. The built-in Standard control configuration supports direct signals from limit switches, thermistors, and external run commands without additional option cards.

Power handling is configured for 400 V grids that can fluctuate between 380 and 480 V without derating, and the heavy-duty rating permits continuous delivery of 2.2 kW to the connected motor. Current is balanced across three phases, and the converter uses standard vector control to help keep torque stable at low speeds. Its integrated EMC filter is specified for industrial installations in class C3 environments, which helps limit conducted interference without external chokes. The housing uses Frame size D, giving the unit a fixed footprint for airflow, mounting clearance, and cable routing inside the cabinet.

Diagnostic and user interaction rely on a standard LCD panel with a potentiometer, so operators can view status information and make local adjustments from the front of the unit. Parameter sets are exchanged via the Modbus interface supported by the control section's Flex-Control with Standard I/O. Protection against accidental restart is provided by the certified Safe Torque Off function, which removes torque-producing energy from the motor when the safety circuit is triggered. The open housing is rated at IP 20 for installation inside a control cabinet with controlled ambient air. The unit belongs to the EFC 5610 model family, and its I/O terminals keep analog speed references, digital run commands, and STO wiring separated for clearer signal routing.
