Product Description:

The EFC5610-7K50-3P4-MDA-7P-FCPNN-NNNN frequency converter is manufactured by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. Positioned in product line 02, it serves as a compact AC drive that adjusts motor speed by modulating output frequency and voltage. This role makes it suitable for pumps, fans, and material-handling machines where process efficiency and controlled starting currents are required.

Field integration is handled through a Modbus interface, allowing the converter to exchange setpoints and status over a simple two-wire network. Motor control is executed with standard vector control (SVC), and this algorithm maintains torque at low speed without the need for an encoder. Local operation is provided by a standard LCD display with potentiometer, so parameters can be changed or the motor can be jogged directly from the front panel. The power section accepts a nominal supply of 400 V (AC 380…480 V -15% / +10%), matching common three-phase distribution in production plants. Internally, the converter is wired for three phases on both the input and motor sides, ensuring balanced current draw and symmetrical torque production.

An integrated EMC filter rated for industrial area, Class C3 suppresses conducted emissions, permitting installation in environments with sensitive instrumentation. The mechanical package corresponds to frame size E, giving a consistent footprint for cabinet layouts across the EFC 5610 range. When set to heavy-duty mode, the unit delivers 7.5 kW of motor power, providing headroom for applications that impose frequent overloads or high starting torque. Component access is from the front, and the housing carries a protection level of IP20, so it must be installed inside a control enclosure where ambient dust and accidental contact are already restricted.
