2) Optional terminal input
You can input the signal into optional terminals as same as anarog input.
See the section 6 for detail of input characteristic setting.
AI1: differential current input
AI2: voltage / current input
3) PG feedback input
It is used in speed PID control mainly.
Input by single-phase pulse in case of PG feedback for PID control.
Set pt (V/f control mode selection) except 7: PG feedback control and 8: PG feedback vector
control<VF-AS1 only>.
See the manual E6581319 for detail of PG feedback option.
