Bosch Rexroth EFC 3600 VFD boasts energy efficient process control

Dec. 6, 2016 – Bosch Rexroth says its EFC 3600 variable frequency drive (VFD) series complements its existing product portfolio including the Fe and Fv frequency converters and the IndraDrive platform.

The EFC 3600 claims to improve 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, says the company. Boasting an intermittent overload capacity of up to 200 per cent and initial torque of up to 150 per cent, the EFC 3600 can be used for a range of applications with varying requirements. The freely scalable V/Hz characteristic allows load-dependent adjustment of the voltage/frequency curve, which ensures a longer motor service life, adds the company. The EFC 3600 can be connected to other automation topologies via optional Modbus or PROFIBUS fieldbus interfaces or via digital and analogue inputs and outputs. It is offered covering the performance spectrum from 400W to 4KW (0.5 hp to 5 hp).
