DIP Switch S1 Analog Input Signal Selection

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