Product Description:

The EFC3610-15K0-3P4-MDA-7P-NNNNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat as part of the EFC Frequency Converters series. This unit converts fixed mains input into a variable output frequency and voltage so that induction motors can be matched to process demands in conveyors, pumps, and general machinery. Its built-in power electronics, control section, and standard I/O enable stand-alone speed regulation or integration into a wider drive system where precise adjustment of motor speed is required for energy savings and process consistency. By varying motor speed electronically, the converter can reduce abrupt starts and support smoother process changes in equipment that does not require full servo control.

It accepts a mains supply of 400 V (AC 380…480 V -15 % / +10 %) across three conductors and delivers up to 15.0 kW of output power in heavy-duty operation. Motor flux is managed through Enhanced V/Hz control, a scalar method that maintains the voltage-to-frequency ratio for constant torque at low and nominal speeds. For supervisory communication, it supports Modbus, allowing parameter access or remote run commands from PLCs. Mechanical integration is simplified because the converter is built on the compact F frame size, keeping panel depth moderate while providing space for the required power components. This control approach suits many common industrial loads where dependable speed regulation is more important than highly dynamic motion response.

In addition to the core features above, the device includes an integrated EMC filter rated for Industrial area, class C3, which helps limit conducted emissions on supply lines. Its housing carries an IP20 protection class that helps prevent accidental contact with live parts when mounted inside a cabinet. A front-mounted Standard LCD display with potentiometer permits local setpoint entry, status viewing, and quick fault diagnostics without external tools. The output stage is designed for three-phase motors, so balanced current sharing is maintained under variable load conditions. The local display also allows basic operating adjustments at the drive itself when a separate operator interface is not used.
