%
The percentage of the voltage at pin 17 based upon the
High and Low settings, i.e., the percent of:
((analog_input_volts_18) – (analog_input_18_low)) /
((analog_input_18_high) – (analog_input_18_low))
Voltage Throttle usage: reference the Forward Min/Max & Reverse
Min/Max Input parameters located in the Application Setup »
Throttle menu.
Brake input usage: reference the Brake Min/Max Input
parameters located in the Application Setup » Brake menu.
Low
Analog_Input_18_Low
0x3309 0x00
0.0 – 11.0 V
0 – 1100
0.0 V The minimum input voltage before a fault is declared. When the
Analog 18 Type selection is voltage, this set point represents the
0% point for the normalized input.
Triggers the Throttle Input fault (0x2210) when the voltage reading
is below this input voltage reading, if Throttle_Source = 18.
Triggers the Brake Input fault (0x2310) when the voltage reading
is below this input voltage reading, if Brake_Source = 18.
High
Analog_Input_18_High
0x330A 0x00
0.0 – 11.0 V
0 – 110
5.1 V 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.

Analog_Input_18_Type
0x330F 0x00
3Wire 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 (pin 17) and is paired
with Analog 19 (pin 27) as the wiper 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 Type
Analog_Input_18_Type

2Wire 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, pin 17 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.,
pin 7). The Programmer app will automatically adjust the menu to
match this parameter conguration.
