These intelligent frequency converters - commonly known as variable frequency drives (VFD), AC drives or variable speed drives (VSD) - control speed as demanded, significantly reducing the energy consumption of pumps, compressors and fans. They can be integrated into many types of applications and machines as compact units for speed and torque control. Integrated energy counters measure actual consumption and capture valuable information for the energy usage optimization of machines and systems. With the integrated control panel, commissioning can be done easily without external programming devices or a PC. From there, the user can start auto-tuning and enter, change or backup parameters. With switchover options between parameter sets and integrated PID control to increase flexibility, as well as extensive connectivity options like Multi-Ethernet interface option (Sercos, EtherNet/IP, PROFINET, EtherCAT, and Modbus/TCP), designated fieldbus options (Profibus DP and CANopen) and additional I/O options, the devices are suitable for most machine applications. The removable LED operator display panel shows all operating variables and has an integrated copy function. This accelerates the commissioning of several frequency converters with the same or similar parameter set and reduces the work required when exchanging equipment or in series production.
