Product Description:

The EFC5610-1K50-1P2-MDA-NN-NNNNN-NNNN is a frequency converter built by Bosch Rexroth Indramat within the EFC Frequency Converters series. It is intended to modulate the speed of standard three-phase induction motors in automated machinery by adjusting the output frequency and voltage delivered to the load. The device serves as the interface between the plant’s single-phase mains and the motor circuit, providing variable-speed control that supports energy efficiency and process consistency in conveyors, pumps, and material-handling cells.

Electrical parameters describe how the converter integrates with the supply network and the driven motor. It accepts a single-phase input of 1 AC 200/240 VAC at 50/60 Hz and draws up to 16.2/13.5 A, depending on line voltage. Internally, it can deliver 7.3/6.1 A to the motor, equivalent to 2.5 kVA of apparent power and a rated mechanical output of 1.5 kW. Frequency synthesis is possible from zero up to 400 Hz, allowing oversynchronous operation when required. Control and diagnostics are handled through RS485 with Modbus protocol, while the logic electronics are powered from a 24 VDC, 200 mA auxiliary supply.

Thermal and protective features support reliable service on the factory floor. The converter uses forced-air cooling and releases up to 120 W of heat that must be extracted from the cabinet. Input protection is provided by a gG fuse rated at 25.0 A, and the embedded electronics support an encoder or counter interface with a pulse frequency up to 32.0 kHz. Functional safety is addressed by the integrated Safe Torque Off circuitry, which removes drive power without using external contactors. Installation details include a recommended power-cable cross-section of 4.0 mm² and a terminal tightening torque of 1.00 N·m, both of which help maintain conductor integrity under vibration.
