Product Description:

The EFC5610-37K0-3P4-MDA-7P-00002-L1NN is an AC frequency converter produced by Bosch Rexroth Indramat for the EFC Frequency Converters series. Classified under product line 02 and belonging to the EFC 5610 model group, the device is mounted inside control cabinets where forced-air cooling is available. In automated factories, it is placed between the plant power bus and an asynchronous motor, synthesizing a variable output frequency so that pumps, fans, or material-handling drives can match commanded speeds, reduce energy consumption, and lower mechanical stress during start-ups and deceleration.

Incoming power is rated at 400 V (AC 380…480 V -15% / +10%), so the converter can be wired directly to common industrial distribution without an isolation transformer. It is intended for three-phase power and employs standard vector control (SVC), allowing stable torque production at low speeds by regulating current vectors rather than relying only on open-loop volts-per-hertz control. In heavy-duty mode, it supports motors up to 37.0 kW, which sets the maximum continuous output level and the thermal margin of the power stage. The electronics sit behind an enclosure rated IP20, meaning fingers are guarded but the installation cabinet must provide the overall dust and water protection.

Parameter access and diagnostics are handled through the built-in standard LCD display with a potentiometer, while remote adjustments and monitoring travel over the Modbus serial protocol provided on the control terminals. The Flex-Control section with Standard I/O issues discrete and analog signals for start, speed reference, and status feedback, and its frame size H aligns mounting holes with other drives in the range. For electromagnetic compatibility, the unit ships with an integrated filter qualified for industrial area, Class C3, which keeps conducted emissions within limits for non-public supply networks. When a risk-graded stop is required, the power stage can disable torque through the certified Safe Torque Off (STO) function without external contactors.
