The characteristics is plus when selecting minus characteristics both [F359] setting and input terminal,
2) Optional terminal input
You can input the signal into optional terminals [AI4] and [AI5] as same as analog input.
Refer to chapter 6 for detail of input characteristic setting.
3) PG feedback input
It is used in speed PID control mainly.
Set [Pt: V/f pattern] to except "10: PG feedback control" or "11: PG feedback vector control".
Example of feedback value setting
Calculate the input pulse frequency to percent base data by the following.
Set the parameters of 2 input points.
