P2.4.2 175 AI1 Signal Range 1,2,3 RW
Configures the Analog input 1 signal source scaling.
0 = 0-100%/0-20mA/0-10V - 0-100% is equal to 0 to 10V, 0-20mA.
1 = 20-100%/4-20mA/2-10V - 20-100% is equal to 2 to 10V, 4-20mA.
2 = “Customized,” see parameter Para ID 176 and 177, this defines the customized signal range.

P2.4.3 176 AI1 Custom Min 1,2,3 RW
Defines the custom minimum range of the analog input scale when the signal range is set for custom.
AI1 Custom Min < = AI1 Custom Max.
P2.4.4 177 AI1 Custom Max 1,2,3 RW
Defines the custom maximum range of the analog input scale when the signal range is set for custom.
AI1 Custom Min < = AI1 Custom Max.
