Product Description:

The EFC3610-11K0-3P4-MDA-7P-NNNNN-NNNN is a frequency converter manufactured by Bosch Rexroth Indramat and supplied within the EFC Frequency Converters series. As part of the EFC 3610 model family and product line 02, it is designed to modulate the speed of standard induction motors in automated machinery by adjusting stator frequency and voltage. The unit sits in frame size F and targets pump, fan, and conveyor drives that require consistent torque regulation without integrated safety functions.

The converter is engineered for a mains connection of 400 V AC (380 to 480 V, -15% to +10%) across three incoming phases, enabling use on common industrial supply networks. When configured for heavy duty, it can deliver 11.0 kW of shaft power to the connected motor. Speed is set through enhanced V/Hz control, an open-loop method that improves low-speed torque compared with basic scalar schemes. Communication with higher-level PLCs or HMIs is provided through Modbus, so drive parameters can be read and adjusted over a two-wire serial link. Protection class IP20 indicates that fingers and similar objects are kept away from live parts. The drive must be installed in a closed cabinet for dust or liquid protection.

The integrated EMC filter is rated for industrial area, Class C3, which suppresses conducted emissions to levels acceptable in heavy industrial zones. Power flows through a three-phase input rectifier, and operating data are shown on a standard LCD display with potentiometer for local monitoring and quick manual speed adjustments. Internally, commands reach the inverter through a Flex-Control with standard I/O section, which provides discrete terminals for run, fault reset, and analog reference signals. The standard control configuration is preloaded, and no variant-specific hardware modifications are present.
