Product Description:

The EFC5610-18K5-3P4-MDA-7P-FCPNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. Mounted inside a control cabinet, it varies motor speed by adjusting output frequency and voltage to match process demands in automated lines and material-handling equipment. The unit is part of the EFC 5610 model series and Product Line 02, making it suitable for compact cabinet installations that need motor control and integrated safety functions. Its operating role is to provide stable variable-speed control for three-phase motors used in routine industrial motion and process tasks.

The converter accepts a supply of 400 V (AC 380…480 V -15 % / +10 %) across a three-phase mains and uses a Flex-Control section with Standard I/O to deliver speed-regulated output. Network integration is provided through Modbus, allowing parameter access from PLCs and other compatible control devices without extra gateways. Drive algorithms rely on Standard Vector control SVC, which improves torque response at low speeds compared with scalar methods and helps the motor run more smoothly during load changes. To limit conducted interference on long motor cables, an internal EMC filter rated for Industrial area, class C3 is fitted. The mechanical layout uses Frame Size G, which sets the overall height and the terminal spacing for power conductors.

For heavy-duty cycles, the drive supports a motor rating of 18.5 kW, so it suits mid-range pumps, fans, and mixers that demand continuous torque at elevated ambient temperatures. Hardware protection reaches IP 20, which provides touch-safe construction and requires installation in a closed electrical enclosure where dust or liquids may be present. The integrated safety channel provides Safe Torque Off (STO), disabling output power through redundant logic during emergency stop conditions. Local setup is handled from a Standard LCD display with potentiometer, which combines text-based parameter access with a manual reference knob for direct speed adjustment. This arrangement supports routine operation when quick local changes are needed at the cabinet.
