Product Description:

The EFC5610-4K00-3P4-MDA-7P-NNNNN-L1NN frequency converter is manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. Classified in product line 02 and identified in the EFC 5610 model series, this unit serves automated plants that require adjustable motor speed and torque. Within such installations, it functions as the final power stage between the control PLC and the motor as part of a standard drive chain used on conveyor modules, fan arrays, and similar motion duties in industrial automation. By varying output frequency and voltage, the converter allows connected motors to respond more closely to changing process demand than fixed-speed operation allows.

The converter accepts a mains supply of 400 V (AC 380 to 480 V -15% / +10%) delivered over three phases, so it can be wired directly to typical factory power systems. Speed regulation is executed with standard vector control SVC, giving stable torque at low frequencies without encoder feedback. This control method supports smooth acceleration and steady low-speed operation in common industrial transport and ventilation tasks. Parameter sets and diagnostics are exchanged over Modbus, allowing integration into existing SCADA loops. The electronics are housed in frame size D, a mechanical format that sets the mounting pattern and cable clearance inside a control cabinet.

In heavy-duty mode, the unit can energize motors up to 4.0 kW, while its EMC filter is rated for Industrial area, class C3 to help limit conducted emissions on long cable runs. The housing carries an IP20 protection class, so it must be installed inside an enclosure while still providing touch protection at the device surface. Machine safety is supported by the integrated Safe Torque Off (STO) channel, which removes torque-producing energy without relying on relays in the main circuit. The drive also includes a standard control configuration with Flex-Control and standard I/O, and user interaction is provided through a standard LCD display with a local potentiometer for quick setpoint entry.
