Variable frequency drive for energy efficient process control
Bosch Rexroth's EFC 3600 variable frequency drive series is designed to improve the process controls through integrated PID controllers as well as a sequence control system with eight steps.
Bosch Rexroth's EFC 3600 variable frequency drive series is designed general automation, material handling and pumps, fans, and compressors. The EFC 3600 variable frequency drive (VFD) by Bosch Rexroth complements the existing product portfolio including the Fe and Fv frequency converters as well as the IndraDrive platform. The EFC 3600 is designed to improve the process control through integrated proportional-integral-derivative (PID) controllers as well as a sequence control system with eight steps. The settings enable an energy efficient operation of equipment and machines at their optimal operating point. Its high intermittent overload capacity of up to 200% as well as the high initial torque of up to 150% allows the EFC 3600 can be used for a wide range of applications. The scalable V/Hz characteristic allows load-dependent adjustment of the voltage/frequency curve for a longer motor service life.
The EFC 3600 covers the performance spectrum from 400 W to 4 KW. Due to the integrated brake chopper and mains filter, additional peripheral devices are not required. The EFC 3600 complies with the EMC directives for industrial applications. For devices up to 0.75 kW (1 hp), cooling fans are not required and subsequently are supplied without fan. Devices with performance level 1.5 kW (2 hp) and higher are supplied with integrated fans that can be easily accessed without requiring tools for maintenance. The EFC 3600 complements Rexroth's frequency converter series Fe and Fv, which cover the performance spectrum up to 90 kW (125 hp).
