H3-08 Terminal A2 Signal Level
The H3-08 parameter (Terminal A2 Signal Level) allows the programmer to specify the signal that will be applied to the A2
analog input. The A2 analog input can accept either a 0–10 Vdc or 4-20 mA signal as a reference. The Drive also has a
DIP switch (S1) on the removable terminal board that must be set for the proper reference signal into the A2 analog input. The
S1-2 dipswitch setting determines the internal resistance of the A2 input while parameter H3-08 determines how the Drive
interprets the measured signal.
