PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
High
Analog_Input_18_High
0x330A 0x00
0.0 – 11.0V
0 – 110
5.1V The maximum input voltage before a fault is declared. When
the Analog 18 Type selection is voltage, set point represents the
100% point for the normalized input.
Triggers the Throttle Input fault (0x2210) when the voltage reading
is above this input voltage reading, if Throttle_Source = 18.
Triggers the Brake Input fault (0x2310) when the voltage reading
is above this input voltage reading, if Brake_Source = 18.
Fault Tolerance
Analog_Input_18_Fault_
Tolerance
0x337A 0x00
0.0 – 11.0V
0 – 1100
0.0V Species the voltage threshold above the congured high limit
or below the low limit, exceeding this results in an analog out of
range fault.
For example, if High = 9.6V, Low = 1V and Tolerance = 0.2V, an
input voltage between 1V to 9.6V is mapped to 0–100%.
Voltages above 9.8V (9.6 + 0.2) or below 0.8V (1V – 0.2V) trigger
the fault.

Parameters for 3-Wire Pot selection Reference the 3-wire potentiometer throttle section, Chapter 6.

Analog 18 Type
Analog_Input_18_Type

3 Wire Pot
(selection menu)
– Selection of the 3-Wire Pot opens the Nominal Resistance parameter.
Note: When conguring Analog Input 18 as a 3-wire Potentiometer
input, it becomes the wiper (Input 18) and is paired with Analog
19 (Input 19) as the potentiometer wiper’s 5V supply voltage
(high). The Programmer app will automatically adjust the menu to
match this parameter conguration.
Nominal Resistance
Pot_18_R
0x3357 0x00
800 – 15000 Ω
800 – 15000
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 = 18.
Note: If this parameter value is outside the actual resistance, it will
trigger a Brake Input fault (Flash code 0x44) if Brake_Source = 18.
Analog 18 menu
Parameters for 2-Wire Pot selection Reference the 2-wire potentiometer throttle section, Chapter 6.
Potentiometer 18
Analog 18 Type

2 Wire Pot
(selection menu)
– Selection of the 2-Wire Pot opens the Nominal Resistance parameter.
Note: when conguring Analog input 18 as a 2-wire Potentiometer
input, the connection (pin) is both the voltage supply and 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_18_R
0x3357 0x00
800 – 15000 Ω
800 – 15000
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 = 18.
Note: If this parameter value is outside the actual resistance, it will
trigger a Brake Input fault (Flash code 0x44) if Brake_Source = 18.
