Product Description:

The EFC3610-5K50-3P4-MDA-NN-NNNNN-NNNN is manufactured by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. This variable-speed AC drive controls the frequency supplied to standard induction motors so automated material-handling, pumping, and ventilation equipment can match speed to process demand and reduce energy waste. It is suited to applications that need adjustable motor speed rather than precise servo positioning. Its control method also fits pumps and fans that benefit from smooth speed changes under varying load.

Within the EFC 3610 model series, the converter communicates through Modbus, allowing a PLC to exchange status words and setpoints without additional gateways. Torque production is handled by Enhanced V/Hz control, a scalar scheme that boosts low-speed voltage for improved motor response. The power stage accepts a nominal line of 400 V (AC 380…480 V -15% / +10%) on three-phase power, making the unit compatible with common industrial mains. Heavy-duty applications can be mounted consistently because the hardware uses frame size E dimensions. A dust cover replaces the keypad, so setup is performed through the terminal strip or a PC, while the control configuration is standard and the internal logic board is assigned to product line 02.

The output stage delivers up to 5.5 kW when operated on the heavy-duty curve, providing brief 150% overload capability without derating. Electronics are housed behind an IP20 enclosure and therefore must be installed inside a ventilated panel. Conducted emissions are limited by the integrated filter graded as Industrial area, class C3, aligning the drive with installations that use long motor cables and high switching frequencies. I/O expands through the Flex-Control with Standard I/O section, which offers programmable digital inputs, a relay output, and analog channels for speed references. These connections allow the drive to accept run commands, fault resets, and speed references from external controls, and no certified safety function is provided, so any required functional safety must be handled by external contactors or other safety hardware.
