PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Low
Analog_Input_1_Low
0x32F3 0x00
0.0 – 11.0 V
0 – 1100
0.0 V The minimum input voltage before a fault is declared. When the
Analog 1 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 = 1.
Triggers the Brake Input fault (0x2310) when the voltage reading
is below this input voltage reading, if Brake_Source = 1.
High
Analog_Input_1_High
0x32F4 0x00
0.0 – 11.0 V
0 – 110
5.1 V The maximum input voltage before a fault is declared. When the
Analog 1 Type selection is voltage, this 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 = 1.
Triggers the Brake Input fault (0x2310) when the voltage reading
is above this input voltage reading, if Brake_Source = 1.

Parameters for 3Wire Pot selection Reference the 3-wire potentiometer throttle section, Chapter 6
Potentiometer 1 (wiper) & 6 (high)
Analog 1 Type
Analog_Input_1_Type
0x32E6 0x00
3Wire Pot
(selection menu)
– Selecting the 3Wire Pot option opens the Nominal Resistance
parameter.
Note, when conguring Analog input 1 as a 3-Wire Potentiometer
input, it becomes the wiper (pin 16) and is paired with Analog 6
(pin 15) as the wiper 5V supply voltage (high). 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 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.
Analog 1 menu
Parameters for 2Wire Pot selection Reference the 2-wire potentiometer throttle section, Chapter 6
Potentiometer 1
Analog 1 Type
Analog_Input_1_Type
0x32E6 0x00
2Wire Pot
(selection menu)
– Selecting the 2Wire Pot option opens the Nominal Resistance
parameter.
Note, when conguring Analog input 1 as a 2-Wire Potentiometer
input, pin 16 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.
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.
