Intelligent inverter VF66B


The VF66B inverter lets you implement all your ideas, including energy conservation, thanks to its host of applications, customizable functionality, and PC tools that support design and testing.


Customizable functionality for your system (built-in PLC function)

The built-in PLC function of the VF66B has 18 control blocks, 36 dataflow blocks, and 5 ladder blocks—and with customized combinations, can be configured for any type of control system you want.
(Program capacity is 16 kB for about 1,024 steps)
