Product Description:

The EFC3610-7K50-3P4-MDA-7P-NNNNN-NNNN is a frequency converter manufactured by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. As a drive component, it varies the speed of three-phase induction motors in automated machinery by adjusting output frequency and voltage. This compact cabinet-mount unit is intended for industrial systems that require controlled motor speed in a space-efficient installation. It suits conveyors, fans, pumps, and similar machine functions where smooth speed changes improve process control. By adjusting motor speed to match demand, the converter can reduce unnecessary mechanical stress during starts and running changes.

The unit connects to mains supplies rated at 400 V and operates across 380 to 480 V with a -15% to +10% tolerance. It delivers up to 7.5 kW of motor power in heavy-duty service for equipment that needs steady variable-speed operation. The enclosure uses frame size E, which keeps its mounting pattern consistent with other E-sized drives in the series. Its housing carries an IP20 rating, so it is intended for installation inside a closed electrical cabinet rather than in open exposure. A built-in EMC filter rated to Class C3 helps reduce high-frequency emissions, and the standard control arrangement leaves emergency-stop handling to external contactors. This enclosure style supports vertical cabinet mounting where surrounding components can share the same protected interior.

Communication is handled through Modbus messaging, allowing parameter access over RS-485 while the onboard I/O manages start, stop, and speed commands. Higher-level controllers can send speed references while the drive retains local control functions for basic operation. Motor behavior is controlled by the Enhanced V/Hz control method, which scales voltage with frequency to maintain magnetizing current across the operating range. Status is shown on a Standard LCD display with potentiometer, so the front panel can be used for local monitoring and speed adjustment. The converter uses three phases for its power input, matching common industrial supply arrangements.
