H4 Analog Outputs - YASKAWA F7 Programming Manual

An analog input filter can be used to prevent erratic Drive control when a "noisy" analog reference is used. Parameter H3-12
sets the time constant for a first order filter that will be applied to both the A1, A2, and A3 analog inputs. The Drive operation
becomes more stable the longer the time programmed, but it becomes less responsive to rapidly changing analog signals.

H4-01 Terminal FM Monitor Selection
Setting Range: 1 to 45
Factory Default: 2: Output Freq
The FM and AM analog output terminals can be programmed to output a 0 to 10 Vdc, -10 to +10 Vdc, or 4 to 20 mA signal
proportional to any one of functions detailed in the table below.
