Dec. 9, 2016 – Bosch Rexroth says its EFC 3610 and EFC 5610 frequency converters are “scalable in performance and functioning,” and can be integrated into a “wide variety” of automation environments with open interfaces.
Commissioning can be done without programming devices or a PC. The intelligent frequency converters control speed on demand, and can “significantly” reduce energy consumption of pumps, compressors and fans. They can be integrated into many different kinds of machines as compact units for speed and torque control. Together with permanent magnet motors, the frequency converters promise to increase energy efficiency and the continuously adaptable pulse frequency minimizes motor noise. The two frequency converter series cover the power spectrum from 0.4 to 18.5 kW. In addition to the freely definable V/f operation, the EFC 5610 boasts vector control for an optimal torque curve. In heavy duty mode, the overload capacity can be maintained at up to 150 per cent for 60 seconds, says the company. Meanwhile, the EFC 5610 frequency converter also offers an optimal start torque of 200 per cent at 0.5 Hz.
