The electronic frequency converter series EFC 3600 by Rexroth offers an economic solution for energy efficient oriented process control application.
Variable speed control for electronic drives is a main factor for increasing energy efficiency in machine engineering. With the EFC 3600 variable frequency drive series, Bosch Rexroth offers the economic benefits for general automation, material handling and pumps, fans and compressors, which had up to now been operated continuously and inefficiently.
EFC Bos 3600变频驱动器(VFD)ch Rexroth complements the existing product portfolio including the Fe and Fv frequency converters as well as the highly dynamic IndraDrive platform. The EFC 3600 improves the process control through integrated PID controllers as well as through a sequence control system with eight steps. The settings enable an energy efficient operation of equipment and machines at their optimal operating point. Due to its high intermittent overload capacity of up to 200 percent as well as the high initial torque of up to 150 percent, the EFC 3600 can be used for a wide range of applications with the most varying requirements. The freely scalable V/Hz characteristic allows load-dependent adjustment of the voltage/frequency curve, which ensures a longer motor service life.
EFC 3600可以通过可选的Modbus或Profibus FieldBus接口或通过数字和模拟输入和输出连接到其他自动化拓扑。提供EFC 3600，涵盖了400 W至4 kW（0.5 hp至5 hp）的性能频谱。由于集成的制动斩波器和电源过滤器，不需要其他外围设备。EFC 3600符合工业应用的EMC指令。
The simple program structure and easy parameter input provide for quick commissioning and start-up without the need for a PC. Harmonized parameters apply to all converters of the series. With the removable control panel function, the user can quickly configure several electronic frequency converters. This also reduces integration- and downtime in case of system expansion or in case of replacement. The service technician would simply use the control panel and copy the existing parameters to the new device.
Due to its compact design which is complemented by the pluggable I/O terminals and optimized cooling concept, a gapless side-by-side and space-saving installation is possible. 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).
