Product Description:

The EFC5610-0K40-3P4-MDA-7P-FCPNN-L1NN is an AC frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. It installs in a control cabinet and modulates the voltage and frequency supplied to a three-phase induction motor so that machine speed follows process demand. By transforming fixed mains power into a variable output, the device supports energy-efficient control of pumps, fans, and material-handling equipment in general automation.

At a 380 V three-phase supply, the converter draws a maximum input current of 1.5 A and delivers 1.3 A to the motor terminals. A separate control board is powered from a 24 VDC auxiliary rail that requires only 200 mA, allowing low-power logic circuits to stay active during mains isolation. The default carrier frequency is set to 6 kHz; this switching rate balances acoustic noise against semiconductor heating. Line-side protection is provided by a 6.0 A fuse, while internal losses are limited to 20 W and removed through natural cooling without forced airflow. Field wiring lands on spring clamps tightened to 1.00 N·m, preserving contact integrity under vibration.

During rapid deceleration, the integrated brake chopper activates once the DC-link reaches 770 V, redirecting excess energy to an external resistor. Motor matching for small conveyors or dosing pumps is supported by a nominal shaft power of 0.4 kW and an apparent output capacity of 0.9 kVA. The pulse output stage can generate feedback signals up to 32.0 kHz for counters or high-speed PLC inputs, while the control bus uses an RS485 port that communicates through Modbus for command and diagnostics. An enclosure classification of IP20 indicates finger-safe openings but no liquid protection, making this model suitable for clean switchgear rooms.
