Product Description:

The EFC3610-1K50-3P4-MDA-7P-NNNNN-NNNN belongs to the EFC Frequency Converters series produced by Bosch Rexroth Indramat. This frequency converter modulates the supply frequency delivered to induction motors so that speed and torque match process demand in automated machinery. It is intended for installation in a control cabinet and uses the same mounting pattern as other drives in the series. That arrangement supports compact machine layouts for OEM equipment that requires a small drive footprint.

The unit operates on a mains supply centered at 400 V AC, with an allowable range of 380 to 480 V and a tolerance of -15% to +10%, so it can be connected to common plant power. In heavy-duty mode, it supports motors up to 1.5 kW, which suits pumps, small conveyors, and indexing tables. Communication with a higher-level PLC is handled through Modbus, allowing parameter access over a simple two-wire bus. Torque is controlled through Enhanced V/Hz control, which improves low-speed performance compared with basic scalar control. For conducted emissions, the built-in filter is rated for Industrial area, class C3, which suits installations where commercial interference limits are not required.

The housing meets IP20, meaning live parts are finger-safe, but the unit still requires installation in a closed enclosure for additional protection. Power terminals accept a three-phase supply, and optional line reactors can be added on the input to improve harmonic behavior. The housing uses Frame Size C, so its drilling template matches other C-frame devices in the product line. Operators interact through a Standard LCD display that includes an integral potentiometer for quick speed adjustment. The control configuration is standard, the Flex-Control section provides eight digital and two analog I/O points, and the product line code is 02.
