DIP Switch S1 Analog Input Signal Selection

The main frequency reference can either be a voltage or current signal input.
To use current input at terminal A1, set the DIP switch S1 to "I" (default setting) and set
parameter H3-01 = "2" or "3" (4-20 mA or 0-20 mA).
When using as a voltage input, set DIP switch S1 to "V" (right position) and program
parameter H3-01 to "0" (0 to +10 Vdc with lower limit) or "1" (0 to +10 Vdc without lower
limit).
