Variable frequency drive AFV2000 series in brief …
To vary the power frequency in order to obtain the resonance condition between the output frequency of the power supply and the natural oscillation frequency of the vibrating system (coil, springs, container, etc.) with our drives you just have to act on 4 rotary switches on the front, which, from left to right, define hundreds, dozens, units and tens of Hz.
Alternatively you can modify voltage and frequency via RS485 Modbus serial communication
Since this adjustment can be carried out while the system is running, within minutes you can determine the optimum frequency to get the best performance from your system.
KNOW THE BEST CHARACTERISTICS OF SERIES AFV2000
Digital Controls for Standard Vibrating Channels
Dimensions (mm): L 120 – W 75 – H 190 up to 500W (2,5A) and L 120 – W 75 – H 250 up to 1000W (5A)
This family of economical drives compensates for the output voltage at the input voltage variation, keeping the output flow constant. Manages the start/stop, adjusts the amplitude and frequency of the output voltage and has an Inverter OK signal.
They can also be controlled by PLCs, PCs or other external control logic via Modbus RS485 serial communication to facilitate operating parameter settings.
