Energy efficient process control 

15 Jan 2018

The EFC 3600 variable frequency drive (VFD) by Bosch Rexroth improves the process control through integrated PID controllers, as well as through a sequence control system with eight steps. Due to 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. The freely scalable V/Hz characteristic allows load-dependent adjustment of the voltage/frequency curve, which ensures a long 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. The EFC 3600 is offered from 400W to 4KW (0.5hp to 5hp). Due to the integrated brake chopper and mains filter, additional peripheral devices are not required. The simple program structure and easy parameter input provide quick commissioning and start-up without the need for a PC. Its compact design enables gapless side-by-side and space-saving installation. Cooling fans are only required for devices with performance level 1.5kW (2hp) and higher, and 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 90kW (125hp). The EFC 3600 complies with the EMC directives for industrial applications.
