Product Description:

The EFC3600-2K20-3P4-PDA-7P-NNNN is an AC drive manufactured by Bosch Rexroth Indramat within the EFC Frequency Converters series. As a member of the EFC 3610 model line, it is used in industrial automation to adjust motor speed, reduce inrush during startup, and improve energy use for three-phase induction motors on conveyors, pumps, and fans. That makes it suitable for equipment that benefits from gradual startup instead of abrupt line-connected operation. It also supports variable-speed duties where stable motor response is needed during normal process changes.

It operates from 400 V AC (380 to 480 V, -15% / +10%) input and accepts three-phase power, so it can connect directly to common plant distribution. Output voltage is regulated through Enhanced V/Hz control, which maintains a stable voltage-to-frequency relationship to support motor flux under changing load. The housing uses Frame size D, which gives a consistent mounting format and a predictable thermal footprint in control cabinets. The enclosure has an IP20 protection class, so it is intended for installation inside a protected panel. A built-in EMC filter for industrial area class C3 helps limit conducted emissions on the line side, and the control setup is supplied in a standard configuration for general-purpose use.

The heavy-duty rating supports up to 2.2 kW of motor output, allowing the drive to start and regulate modest pumps or compact conveyor sections without derating. Operators interact through the Standard LCD display with potentiometer, which shows real-time values and allows local speed adjustment from the front of the unit. Command and feedback signals are handled by the Flex-Control with Standard I/O interface, so digital inputs, relay outputs, and an analog reference are available without option modules. This arrangement supports basic run commands, status signaling, and speed reference handling without extra interface hardware. The unit is classified as a Frequency Converter and fits routine motor control tasks that require compact installation and straightforward local operation.
