Note
Note trim pot R376 and test point IZO (near jumper JP2). These components are used to set the
“zero crossing” point if necessary. Trim pot R376 is set and locked at the factory and should not
require adjustment. If, when adjusting the ride quality of the car in later steps, you notice a
sharp bump when transitioning from acceleration to steady speed or from steady speed to
deceleration, you may need to adjust zero crossing.
7. Display the iView Virtual Oscilloscope (View > Diagnostics > Virtual Oscilloscope) and
obtain Write Privilege.
8. On the Virtual Oscilloscope, set Test point 1 = Tachometer Signal.
9. Input ADC - Tachometer: Adjust the Input ADC - Tachometer parameter by enter-
ing and sending small negative or positive values until the Test point 1 value is as close
to 0.0 as possible. The ADC adjustment range is from —0.5 to +0.5.
10. Input ADC - Brake current: Set the Virtual Oscilloscope Test Point 1 = Brake Current
Feedback and then adjust the Input ADC - Brake current parameter by entering and
sending small negative or positive values until the Test point 1 value is as close to 0.0 as
possible.
11. Input ADC - Brake voltage: Set the Virtual Oscilloscope Test Point 1 = Brake Voltage
Feedback and then adjust the Input ADC - Brake voltage parameter by entering and
sending small negative or positive values until the Test point 1 value is as close to 0.0 as
possible.
12. Input ADC - Armature current: Set the Virtual Oscilloscope Test Point 1 = Armature
Current Dampened Feedback and then adjust the Input ADC - Armature current
parameter by entering and sending small negative or positive values until the Test point
1 value is as close to 0.0 as possible.
13. Input ADC - Armature voltage: Set the Virtual Oscilloscope Test Point 1 = Armature
Voltage Dampened Feedback and then adjust the Input ADC - Armature voltage
parameter by entering and sending small negative or positive values until the Test point
1 value is as close to 0.0 as possible.
14. Input ADC - Absolute armature current: Set the Virtual Oscilloscope Test Point 1 =
Armature Current Dampened Feedback and then adjust the Input ADC - Absolute
armature current parameter by entering and sending small negative or positive values
until the Test point 1 value is as close to 0.0 as possible.
15. For the next two adjustments, the Armature Current Test must be enabled in order to
shut off the armature current (Please refer to “Armature Current Test Procedure:” on
page 9-105).
16. Input ADC - Motor field current: Set the Virtual Oscilloscope Test Point 1 = Field Cur-
rent Feedback and then adjust the Input ADC - Motor field current parameter by enter-
ing and sending small negative or positive values until the Test point 1 value is as close
to 0.0 as possible.
17. Input ADC - Motor field voltage: Set the Virtual Oscilloscope Test Point 1 = Field Volt-
age Feedback and then adjust the Input ADC - Motor field
voltage parameter by enter-
ing and sending small negative or positive values until the Test point 1 value is as close
to 0.0 as possible.
