H3-09 Terminal A2 Function Selection
The A2 or A3 analog input can be programmed to perform many different functions. The setting of parameter H3-09 and
H3-05 determines which of the following functions the A2 or A3 analog input will respectively perform. The level of the A2
analog input, as a percentage of the maximum input, can be viewed by the U1-16 monitor.
Function: Adds to Terminal A1
Setting: 0
By setting analog input to 0 the level of the analog input will be summed with the level of the frequency reference analog input A1.
Function: Frequency Gain
Setting: 1
Setting analog input to 1 allows the analog input to act as a gain to the frequency reference.
