PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Nominal Resistance
Pot_6_R
0x336C 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 = 6.
Note: If this parameter value is outside the actual resistance, it will
trigger a Brake Input fault (Flash code 0x44) if Brake_Source = 6.

2Wire Pot
(selection menu)
– Selection of the 2-Wire Pot opens the Nominal Resistance
parameter.
Note, when conguring Analog input 6 as a 2-Wire Potentiometer
input, pin 15 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_6_R
0x336C 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 = 6.
Note: If this parameter value is outside the actual resistance, it will
trigger a Brake Input fault (Flash code 0x44) if Brake_Source = 6.

Voltage with Supply
(selection menu)
– The Analog 6 Type “Voltage with Supply” selection operates the
Analog 6 input (pin 15) as a raw voltage input with an internal
pull-up supply voltage.
The output voltage is 10V (approx.) with a 3 mA current limit (to
the external load/device). Reference Table 7.
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_6 (0x3B33), then
processing the value in the VCL program.

V
The analog voltage at the input pin 15.
Percent

0 – 1000
Read Only
%
The percentage of the voltage at pin 15 based upon the High and
Low settings, i.e., the percent of:
((analog_input_volts_6) – (analog_input_6_low)) /
((analog_input_6_high) – (analog_input_6_low))
