10.79 (ID 321) AI1 Custom Setting Minimum
Location in the menu:
P2.2.5
(Local/Remote Control Application, Multi-Step Speed Control Application)
P2.2.17
(PID Control Application)
P2.2.2.4
(Multi-Purpose Control Application, Pump and Fan Control Application)
Use this parameter to adjust the minimum value of the analog input signal between -160%...160% freely.
10.80 (ID 322) AI1 Custom Setting Maximum
Location in the menu:
P2.2.6
(Local/Remote Control Application, Multi-Step Speed Control Application)
P2.2.18
(PID Control Application)
P2.2.2.5
(Multi-Purpose Control Application, Pump and Fan Control Application)
Use this parameter to adjust the maximum value of the analog input signal between -160%...160% freely.
Use the analog input signal, for example, as frequency reference, and set these 2 parameters between 40–80%. In these conditions,
the frequency reference changes between the
Minimum frequency reference
(
ID 101
) and the
Maximum frequency reference
(
ID 102
),
and the analog input signal changes between 8–16 mA.
10.81 (ID 323) AI1 Signal Inversion
Location in the menu:
P2.2.7
(Local/Remote Control Application, Multi-Step Speed Control Application)
P2.2.19
(PID Control Application)
P2.2.2.6
(Pump and Fan Control Application)
Use this parameter to invert the analog input signal.
If this parameter = 0, no inversion of analog input signal takes place.
In Local/Remote Control Application, AI1 is place B frequency reference when parameter
ID 131
= 0 (default).
