The EFC 3600 also provides economic benefits for general automation, material handling and pumps, fans and compressors, which had previously been operated continuously and inefficiently.
The EFC 3600 variable frequency drive (VFD) complements the company’s Fe and Fv frequency converters as well as the IndraDrive platform. The EFC 3600 settings enable an energy-efficient operation of equipment and machines at their optimal operating point. With its high intermittent overload capacity of up to 200% as well as the high initial torque of up to 150%, 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 helps ensure a longer motor service life.
The EFC 3600 can be connected to other automation topologies via optional Modbus or PROFIBUS fieldbus interfaces or via digital and analog inputs and outputs, and is offered covering the performance spectrum from 400 W to 4 KW (0.5 hp to 5 hp).
With the integrated brake chopper and mains filter, additional peripheral devices are not required. The EFC 3600 complies with the EMC directives for industrial applications.
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 replacement. The service technician simply uses the control panel and copies the existing parameters to the new device.
With 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).
