Voltage/3-Wire/2-Wire
0 – Voltage
1 – 3 Wire Pot
2 – 2 Wire Pot
Voltage
0
0 – Voltage: Analog 9 Input used as an analog voltage input
1 – 3-Wire: Analog inputs 9 & 10 used for a 3-wire pot wiper
2 – 2-Wire: Analog Input 9 used as a 2-wire pot.
Note: if using pin 20 input as a virtual switch, set this parameter
to voltage.
Nominal Resistance
Pot_Resistance_Nominal
0x3041 0x00
0 – 15000 Ohms
0 – 15000
0 The resistance (Ohms) across the 2 or 3 wire potentiometer.
This is the value for the 100% (maximum) position.
2-Wire: The external resistance between pin 20 and 8.
3-Wire: The external resistance between pin 21 and 8.
Tolerance
Pot_Resistance_Tolerance
0x3042 0x00
0 – 2000 Ohms
0 – 2000
0 Sets the pot resistance variation of the potentiometer. The
allowance beyond which a fault is declared.
