4.5. Product of Two Speeds (encoder 1 x encoder 2): F02.004 = 4
Both inputs, encoder 1 and encoder 2, are active. Both speeds are multiplied to form the
product, with consideration of the individual scaling of each channel. The final result can once
more be scaled into user-friendly engineering units by means of the special scaling parameters
in parameter group F02.
Besides the actual speeds and the multiplication result, the unit also records minimum and
maximum values of the product.
Preset K1 is related to the absolute speed of encoder 1.
Preset K2 is related to the absolute speed of encoder 2.
Presets K3 and K4 are related to the product of both speeds (encoder 1 x encoder 2)
