Product Description:

The EFC5610-2K20-3P4-MDA-7P-FCPNN-L1NN frequency converter is built by Bosch Rexroth Indramat and belongs to the EFC Frequency Converters series. Within an automation cell, this unit sits between the mains supply and an induction motor, adjusting output frequency so that machine speed follows the required process profile. Its role is to provide energy-efficient acceleration, deceleration, and steady-state speed control for equipment connected to standard three-phase networks. This operating method helps stabilize motor behavior during changing load conditions and supports smooth speed transitions in routine process duty.

The drive is supplied from a mains bus at 400 V (AC 380...480 V -15% / +10%) and fits the medium power frame size D. Field integration is simplified by the built-in Modbus interface, which allows start, stop, and parameter commands from a PLC without separate gateways. Motor flux is managed through standard vector control (SVC), and this control method supports stable torque response across the speed range. Operators can change setpoints locally through a standard LCD display with a potentiometer, which gives direct access to routine operating adjustments at the drive. Conducted emissions are attenuated by an internal filter rated for industrial area, Class C3 environments. This arrangement suits installations that need both networked control and orderly panel integration.

Heavy-duty applications are covered by a continuous motor output of 2.2 kW, coordinated by the controller’s Flex-Control with Standard I/O section that offers configurable digital and analog terminals for field wiring. The housing has an IP 20 protection class, so it must be installed inside a panel and uses natural airflow for cooling. For personnel protection, the unit includes Safe Torque Off (STO), which removes gate signals to the power stage without relying on mechanical relays. The available control and wiring functions support enclosed installations used for conveyor sections, mixers, and pump assemblies where compact drive layout and straightforward signal routing are required.
