Hi guys, hope you are all fine.

I have some questions that confuses me and hope to get the answers from you,

1- If P0701=99 & P840=722.0, then connects DIN1 one time to 24V from the drive and another time to external supply / from DCS, will the drive ON in both cases? If the answer is yes, then what's the difference between these settings and P0701=1 if I'm going to use the switch for starting the drive only?

2- If P0701=1, P0704=99 & P0810 (local/remote) =722.3, then connects DIN4 to 24V from the drive. Now if DIN1 got 24V from the drive will it run? If so, what's the point of P0810?

3- If I set P1000=2, does that mean I'm going to use rheostat with analog i/p 1 (AIN1) to adjust the frequency set-point?

Thanks in advance.
