PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Nominal Resistance
Pot_1_R
0x3356 0x00
800 – 15000 Ohms 5000 Ω Set the potentiometer resistance.
Throttle or Brake potentiometers are typically 1k, 5k, or 10k Ohms.
Note: If this parameter value is outside the actual resistance, it
will trigger a Throttle Input fault (Flash code 0x42) if Throttle_
Source = 1.
Note: If this parameter value is outside the actual resistance, it will
trigger a Brake Input fault (Flash code 0x44) if Brake_Source = 1.

2 Wire Pot
(selection menu)
– Selecting the 2-Wire Pot option opens the Nominal
Resistance parameter.
Note, when conguring Analog input 1 as a 2-wire Potentiometer
input, the connection (pin) is both the voltage supply and the
wiper input. As a 2-wire pot, one side of the potentiometer is left
open (no connection) and the other end is connected to ground
(i.e., I/O Gnd). The Programmer app will automatically adjust the
menu to match this parameter conguration.
Nominal Resistance
Pot_1_R
0x3356 0x00
800 – 15000 Ohms 5000 Ω Set the nominal resistance of the potentiometer.
Throttle or Brake potentiometers are typically 1k, 5k, or 10k Ohms.
Note: If this parameter value is outside the actual resistance, it
will trigger a Throttle Input fault (Flash code 0x42) if Throttle_
Source = 1.
Note: If this parameter value is outside the actual resistance, it will
trigger a Brake Input fault (Flash code 0x44) if Brake_Source = 1.

Voltage with Supply
(selection menu)
– The Analog 1 Type “Voltage with Supply” selection operates the
Analog 1 input as a raw voltage at the pin with an internal pull-up
supply voltage.
The pin’s output voltage is 10V (approx.) with a 3 mA current limit
(to the external load/device). Reference Table 10.
Use this selection for operating resistive devices such as
thermistors and photocells and reading the voltage in VCL
using the Monitor variable analog_input_volts_1 (0x3B2E), then
processing the value in the VCL program.
Voltage
Analog_Input_Volts_1
0x3B2E 0x00
–327.68 – 327.67V
–32768 – 32767
Read Only The analog voltage at analog 1 input (input 1).
Percent
Analog_Input_Percent_1
0x3B39 0x00
0.0 – 100.0 %
0 – 1000
Read Only The percentage of the voltage at the input pin is based upon the
High and Low settings, i.e., the percent of:
[(analog_input_volts_1) – (analog_input_1_low)] /
[(analog_input_1_high) – (analog_input_1_low)]
