VACON® NX All-in-One
Application Guide
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).
Illustration 43: AI1 No Signal Inversion
If this parameter = 1 inversion of analog input signal takes place.
Maximum AI1 signal = minimum frequency reference
Minimum AI1 signal = maximum frequency reference
