Q:

1-       Does Di20-M10B4 have position pulse mode, or only has outer analog voltage?

2-       There are R/S/T power connection points, if I need to input 220V single phase, so I can connect any two phases of them?

A:

1-       Di20-M10B4 has position pulse mode too, you can change to parameter No.4 and No.14 to get it.

2-       Only those smaller than 1KW can connect the 220V single phase, connect to any two phases of R/S/T.
