Frequency converters for leaner automation
January 2016
System Integration & Control Systems Design
Demand-oriented motor control is enabling users to reduce their electricity consumption by up to 80% compared to fixed-displacement drives. Bosch Rexroth has recently added two new models to its range of frequency converters, the EFC 3610 and EFC 5610, to provide intelligent speed and torque control for motors from 400 W up to 18,5 kW.
Bosch Rexroth’s EFC-class frequency converters are open-source, scalable and expandable drive controls that are easily integrated into many different kinds of machines and automation environments, including in pumps, compressors, fans, conveyors, presses and packaging machines.
The EFC 3610 is a universal, low-cost converter for control and demand-oriented energy supply for almost all industry segments. The EFC 5610 is a high-torque solution with efficient, high-performance vector control for specialised requirements and an expanded power range (up to 18,5 kW). Both are available in heavy-duty and normal-duty configurations.
The communications interface of the EFC converters has expanded to include support for Modbus, Profibus and CAN protocols. Pluggable I/O connection terminals and fieldbus modules enable a high degree of expandability and flexibility in the way drive architectures can be configured. Integrated brake choppers and mains filters (EN61800-3 C3) reduce the need for external componentry, enhancing the plug-and-play functionality of these products. Process control is improved through integrated PID controllers alongside an eight-step sequence control system.
Other innovative features, such as the detachable control interface that allows parameters to be dumped into additional drives using the panel’s memory and copy function, enhance the overall usability of the EFCs. Additional braking resistors are available for applications where the controlled motor is required to stop instantly, dissipating the electromotive voltage.
The Bosch Rexroth frequency converter range will soon be expanded to support motors up to 22 kW, and will also include the Ethernet range of communications.
Apart from lowering the electricity bill through reduced and more efficient consumption, frequency converters lower capex by reducing the requirements of the associated switchgear, while also limiting component stress for a longer motor life.
