EFC5610-18K5-3P4-MDA-NN-NNNNN-L1NN

The EFC5610-18K5-3P4-MDA-NN-NNNNN-L1NN, Bosch Rexroth Indramat, EFC Frequency Converters unit delivers 18.5kW of continuous drive power at a 400V connection voltage while occupying a compact control-cabinet footprint. Its integrated Modbus communication module ensures seamless network integration and remote parameterization. Built on proven Rexroth Indramat design principles, the converter features robust firmware optimized for heavy-duty (HD) operation and supports vertical installation for simplified mounting. An onboard sensorless vector control algorithm yields high starting torque and tight speed regulation from startup to rated speed.

This frequency converter incorporates a built-in brake chopper and mains filter to suppress line disturbances and safely handle regenerative energy. It is rated to withstand ambient temperatures from –10 to 55 °C without derating up to 45 °C; beyond this point it applies a controlled performance derating of 1.5 % per °C. Overload capacity reaches 150 % for 60 s and 200 % for 1 s, while its load-dependent PWM scheme optimizes switching losses and acoustic noise. The device supports a speed control range of 1:200 and maintains 200 % start-up torque at 0.5 Hz, all within a degree of protection IP20 enclosure and a pollution degree of 2.

Engineers will appreciate the converter’s Safety Torque Off option, meeting stringent machine-safety requirements without additional hardware, and its ≤90 % RH tolerance for harsh industrial environments. Plug-and-play firmware modules enable application-specific feature sets and rapid commissioning via standard Rexroth tools. Together, these capabilities ensure reliable performance, streamlined integration, and minimized downtime in pumps, fans, conveyor systems, and other demanding automation applications.
