4.2. “Sum Mode” (Encoder 1 + Encoder 2): F07.062 = 1
Both inputs encoder 1 and encoder 2 are active. From both values the unit forms the sum, with
consideration of the individual encoder scaling factors. Where the encoder signal also provides
direction information, this information will be considered by a corresponding sign of the count.
Without direction information (channel A only) both encoder values will be added up. The final
result can once more be scaled into user-friendly engineering units by means of the special
scaling parameters in parameter group F07.
Besides the actual counter value and the sum, the unit also records minimum and maximum
values of the sum.
Presets K1 and K2 are related to the actual counter value of encoder 1 only.
Presets K3 and K4 are related to the actual sum result (encoder 1 + encoder 2)
